Can you bump start an ATV?

Compression Start An ATV Battery. This method is commonly known as bump starting an ATV, or popping the clutch. You basically have to push the quad fast enough so that when you let the clutch out the engine turns over and starts. Most ATV’s are light enough to be pushed by a normal sized adult on flat ground.

How do you start a quad that won’t start?

How do you start a ATV with a dead battery?

If you need to start an ATV with a dead battery, you can choose a few options. These include jumping the battery with jumper cables connected to another ATV, jumpstarting the battery with jumper cables connected to a car that’s engine is turned off, bump starting the vehicle, and using a battery charger.

Why does my quad turn over but wont start?

If an ATV motor turns over, but doesn’t start, and the battery seems to be fine; it’s time to check out your ignition system. First, check out your spark plugs via a physical inspection. Look for any corrosion or gunk on the plug itself, and ensure that there is a small gap present in the spark gap of the plug.

Why does my four wheeler just click when I try to start it?

Your ATV most likely clicks when you try to start it because of the battery. The reasons for this are numerous, from loose connections to a current draw that drains the battery. If the battery is not the cause, the ATV probably has a faulty starter solenoid.

What do I do if I Swamp my ATV?

How do you start a four wheeler with a screwdriver?

Use A Screwdriver

Basically you just hammer a screwdriver into the ignition and turn it on as if it were the key. The screwdriver will brake the pins in the lock allowing you to turn the ignition on. What is this? I don’t recommend this method because you could damage the ignition and not get the quad to start anyway.

How do you start an ATV sitting?

Simply remove the spark plug to spray a little sea foam into the cylinder head through the spark plug hole. After letting it sit a couple hours (overnight if it’s real bad looking), I will try to turn it over with the spark plugs out to make sure everything moves the way it should.

How do you start a quad in the cold?

When you cold-start your ATV, let it sit and idle for 10 minutes to allow the heat from your engine to warm the rest of its operating parts. After you take off, go no faster than about 5 mph for the first few minutes.

Can you push start an automatic?

But the more modern automatic transmissions cannot be push started as a result of the design change. One exception to this is the Classic Mini Automatic (also Austin America). It has an additional pump on the drive side of the clutches so that it can build the necessary pressure to start it.

How To Jump Start An ATV Battery: The Ultimate Guide

If your ATV battery is dead, your engine won’t turn over. If you’re home and have a charger, it’s not a big deal. But if you’re out on the trail, or don’t have a battery charger, dead batteries can be a real pain. Knowing how to jump start your ATV battery can save you a major headache while out on the trail. Most ATV batteries are 12 volts dc, like a car or motorcycle battery.

I’ve used the compression method I talk about below on my quad before, and it does work. I was a couple miles from camp and I shut my engine off to take in the scenery and walk around a bit. When got back on my quad to head back to camp, the dang thing wouldn’t start. I was able to get it started using the bump (compression) method, and I’m sure glad I knew how to do it rather than trying to push the quad all the way back.

Is It The Battery?

First thing is to make sure the battery is really the problem here. Your battery will slowly lose power over time if it has been sitting. The longer the ATV sits without the battery on a charger, the more likely it is that the battery could have died. You really should be hooking the battery up to a charger if it’s going to be sitting for 3 months or more.

If you try your push button start (or turn key start) and nothing happens, the battery may be dead. Make sure your run switch is turned on and your machine is in neutral. If you have a key, the key will need to be in the run position also. Try turning your headlights on if you have them. This can be deceiving because the battery might have enough power to run the headlights but not turn over the engine. But if they headlights (or any other lights) don’t turn on, you can be more certain the battery is dead.

If your engine turn over but very slowly, it may be the battery. The battery might have enough juice to turn the engine, but not fast enough to get it started. You would hear the motor spin a little but then slow down and stop. If you hear just a clicking sound, but the motor doesn’t turn or do anything, it could be the battery. There could also be a loose connection between your battery and starter. Check and tighten the connections to the battery terminals and to the starter.

Once you’re fairly certain it is the battery, you can try jump starting it. If you’re home and have a charger, there may be no need to jump start. Try just charging the battery first. The charger I use is a Ctek Smart Charger found here on Amazon. It’s sold at a good price (around $60-70) and has all the connections for any brand of battery your ATV has. I chose this battery charger because of its price, and how easy it is to use.

Sometimes this happens out on the trail, where you don’t have a charger. Or maybe you don’t have a charger at home. Whatever the case, you could always jump start your ATV using jumper cables or the compression start method.

Compression Start An ATV Battery

This method is commonly known as bump starting an ATV, or popping the clutch. You basically have to push the quad fast enough so that when you let the clutch out the engine turns over and starts. Most ATV’s are light enough to be pushed by a normal sized adult on flat ground. If you can get going downhill, it makes this a lot easier.

Your starter motor is usually what’s used to start the engine. It draws power from the battery to turn the engine over, which fires the spark plugs and gets the engine running. With the compression method, you are using the tires and momentum to turn the engine over.

Here is a step by step of how to do it:

Turn on the key and run switch if you have them

Get the quad into 2nd gear.

Hold the clutch in and get the quad rolling as fast as you can (around 10 mph)

Hop on and quickly let out the clutch

That’s it! You should hear the engine turn over when you do this. If you’re having a hard time you can try giving it some gas as it starts to turn over. The engine should fire up, when it does, pull the clutch back in. That will prevent the machine from taking off on you as soon as it’s running. It might take a few tries to get it done this way, but it does work.

If the tires skid instead of turning the engine over, try going into 3rd gear and repeating the steps. If the tires still skid, try on more solid terrain or somewhere where the tires have better grip. Once the engine is running, it should charge your battery back up.

If your ATV is an automatic, you won’t have a clutch, and may not have a way to select which gear you’re in. The bump start (compression start) method won’t work the same for you. I have seen people put the ATV into neutral, get it rolling, and drop it into drive to start the machine. But I think doing it this way could damage the transmission. I would only do it that way on an automatic as a last resort.

Jump Start An ATV With Jumper Cables

This is pretty straight forward, and is the same method you would use to jump start a car. You can use another ATV battery or even a car battery if that’s all you have. It’s a good idea to wear rubber soled shoes when you work on anything with electricity. The voltage’s and amperage’s of car and ATV batteries aren’t enough to cause serious damage, but it’s a good idea to be careful around the terminals to avoid damage to your vehicle or ATV.

Jump Start An ATV Battery From Another ATV

For this method all you need is a simple set of Jumper Cables like this one I found on Amazon, and another ATV. First, remove the seats to gain access to the battery. Some quads require that you also remove a battery cover. Connect the jumper cables to the good battery first, making sure the positive and negative of the other end of the cables aren’t touching. Then connect to the bad battery.

You should notice a plus sign or red flag on the battery indicating positive, and a minus sign or black flag indicating negative. Connect the negative (black) first, then the positive (red). You can hook the negative (black) end directly to the frame of the ATV, just make sure it is grounded. This can also help prevent a surge in the electrical system that could damage your machine.

Once you have both batteries connected with the jumper cables, you can start the ATV with the good battery. Let the ATV run for a few minutes. This charges your battery a little bit, and helps when you try to start it. Now you can try starting the other ATV. If it starts up, remove the red cable (positive) and then the black (negative), do this for both ATV’s.

You should leave the engine running for a while after a jump start. That will let the battery charge back up a little bit. If you immediately shut the ATV off, you will need to jump start it again. I’d let it run for a good half hour, I usually go ahead and ride it around for a little while, why not?

Jump Start An ATV Battery From A Car

The hook up for this method is the same as ATV vs ATV or car vs car using jumper cables. Hook to the good battery first, negative (black) then positive (red). The car battery and charging system is much stronger than an ATV battery, and could cause damage to the ATV’s electrical system if you turn on the car. This is because the alternator in your car charges batteries at a higher rate than your ATV battery can handle. For this reason, Do Not turn on the car at any time during this jump start. The car battery should have more than enough juice to start an ATV.

After you have the jumper cables hooked up, simply wait a minute, and try turning on the ATV. If it starts up, then you know the battery was the problem. Once the ATV is started, remove the cables from the ATV first, positive (red) then negative (black), and then from the car. I have done this with my truck, just to make sure it will work for you, and it works well.

Jump Start An ATV With A Battery Pack

This is one of the simplest most straight forward methods. But it’s more expensive because you need to have a battery pack in order to jump start the ATV. This method is similar to using jumper cables except instead of hooking your ATV to another ATV or a car, it’s hooked to a pre-charged battery pack. If you don’t want to carry an extra battery pack with you on your quad all the time, this method may not be for you.

The battery pack we use can also charge our smart phones and tablets, so it’s nice to have on a camping trip anyway. And if my four wheeler’s battery ever dies, it’s a super convenient way to get back riding again. The battery pack I use is called a Portable Jump Starter found here on Amazon. It has a built in flashlight and USB ports to charge phones or tablets, or anything that can charge through a USB port. All the cables and things you will need to hook up to your ATV battery are included.

If you have the extra money, or go camping a lot with your four wheeler. This is the best way to get your battery charged again without needing to pop the clutch, or needing another ATV or car nearby. You simply hook the included alligator clips to your battery, and then hook the cable to the battery pack. Once everything is connected, try to start the engine. The engine should start right up. You may have to wait a couple minutes to let the battery charge a little bit.

It’s always best to never need to jump start your ATV, but it happens sometimes. Taking care of your batteries and keeping them properly charged will save you a headache in the long run.

ATV Won’t Start – Troubleshooting the Most Common Causes

This guide will help you troubleshoot the most common causes for an ATV that won’t start. Some issues are easy to fix at home, while others require assistance from a mechanic.

These are the main reason why an ATV will not start:

The ATV is not getting a spark or is only getting a weak spark

The ATV is not getting fuel

The ATV is not getting enough air

The battery is bad or not charged

The kill switch is bad or corroded

To identify what is causing your ATV’s starting issues, you need to notice how it behaves when yore trying to start it. Choose the topic below that describes your bikes behavior best to begin your troubleshooting.

The ATV won’t start – the engine is not turning over

If your ATV doesn’t crank at all when you’re trying to start it, there are a few basic things to look into.

1. Make sure the kill switch/run switch is in the “ON” or “RUN” position.

You’d be surprised how often the solution to an ATV that won’t start is forgetting to turn on the kill switch.

Also, if your ATV has a tether pull cord style kill switch, make sure it is connected properly.

2. Make sure the ATV is in “Park” or Neutral

Many ATVs are designed not to start when in gear as a safety precaution.

3. Make sure the battery is charged

The battery should read 12,6 – 12,8V. Use a multimeter or a voltmeter to check the voltage.

If the voltage drops too low, the battery won’t have enough charge to start the bike.

Charge the battery or replace it if it’s dead. Am easy way to test your battery is by checking the voltage-drop with a multimeter as you try starting the bike. If your fully charged battery drops below 11,5 volts under load (while you crank the starter), it needs to be replaced.

4. Check the main fuse

Most ATVs have a main fuse. Your user manual will help you locate it.

If your battery is charged, but you still get nothing when turning the key, you may have a blown main fuse. Replace it with the right size fuse and try starting again.

5. Make sure the solenoid is getting power

The solenoid works as a switch that sends a high current to your starter when you push the start button or turn the key. For it to work, you need to make sure it is getting power from the battery.

The solenoid should make an audible “clicking” sound each time you hit the starter. If it does, you know it is getting power, and the problem is likely with the solenoid itself or possibly the starter. Solenoid and starter issues will be covered later in the post.

If you do NOT hear a clicking sound, you can use a multimeter or voltmeter to verify that the solenoid is, in fact, not getting power.

The solenoid is usually located near or on the starter.

Put your multimeter to DC Voltage.

The red lead goes to the battery (red) side of the solenoid.

The black lead goes to ground.

You should get a voltage reading of 12V or more.

If you don’t get a reading, you need to trace the wiring back to your battery to wind where the connection is broken. Look for loose or corroded terminals or shorts from damaged cables.

The ATV won’t start but turns over

A gasoline engine needs three essential components to start and run:

Gasoline

Spark

Air (compressed)

1. Check if the bike is getting fuel

Locate your spark plug. You may need to remove a few plastic covers to find it.

Remove the spark-plug wire (on a carbureted ATV) or the ignition coil (on a fuel-injected ATV) from the spark-plug.

Remove the spark-plug from the cylinder head using a spark-plug removal tool.

If the plug it’s wet, you know the bike is getting fuel.

If the plug is dry, the bike is not getting fuel and you need to continue the troubleshooting as described below.

2. Check for spark

Install the spark plug back into the cylinder head.

Connect an inline spark-tester between the spark plug and the spark-plug wire/ignition coil. You can get one for cheap at most auto supply stores.

Make sure the run switch is in the “ON” position.

Please keep your hands clear of the test tool and the area around it.

Push the starter button.

The test-light on the spark-tester will light up if there is a spark.

Alternative method: If you don’t have a spark tester tool, you can do a visual test to check for spark. Please note that this method may cause electric shock if done incorrectly.

Remove the spark plug from the cylinder-head and connect it to the spark-plug wire or ignition coil.

Grab the plug wire and hold the plug about 1/8th of an inch away from the cylinder head. Make sure you are only touching the rubber and not any metal parts.

Activate the starter.

You should see repetitive bright blue spark arching from the spark plug to the cylinder head as the motor turns.

You will find the proper steps for troubleshooting an ATV that is not getting a spark further down this post.

The ATV is not getting fuel

If the spark plug is still dry after cranking the engine for a few seconds, you know that fuel, for some reason, is not getting to the cylinder.

It’s often either an issue with the fuel-pump or that the fuel supply line is clogged up somewhere between the gas tank and the carburetor.

Old or unstabilized gas tends to gum up over time and may create a clog. Dirt and debris getting inside the tank is another common culprit for a clogged-up fuel supply.

The easiest way to identify the cause is through a process of elimination.

Note that if you find contamination such as dirt or gummed-up fuel at one spot, the whole system is likely dirty and needs a complete clean for the best result.

The steps involved are slightly different depending on whether your ATV has EFI (electronic fuel injection) or a traditional carburetor system.

Both carburated and fuel injected ATVs: Make sure the gas cap vent is not clogged

There is either a vent in the gas cap or a separate gas tank vent tube. Make sure neither is clogged and allows air to flow freely.

Fuel needs to be replaced with air as it gets pumped out and used. If the vent is blocked, the fuel pump may not be able to suck fuel out of the tank.

When a carbureted ATV is not getting fuel

Older ATVs, and some of the cheaper models still today are designed with a traditional carburetor fuel-system.

1. Make sure the fuel shut off valve is in the “ON” position

There should be a shut off valve at the lowest part of the fuel tank. Make sure it is turned on.

2. Check if the carburetor is getting fuel or not

This step will help you narrow down the possible causes of why fuel is not reaching the cylinder.

With the fuel valve open, disconnect the fuel line from the fuel inlet of the carburetor. Turn over the engine to see if gas is coming through the fuel line.

If it is very little or no fuel coming from the fuel line, you likely have either:

A clogged up or faulty shut-off valve.

A clogged-up fuel filter.

A fuel-pump problem.

A clogged gas cap or gas tank vent.

If there is a steady or pulsating stream of fuel you know that

The fuel pump is ok.

Fuel flows all the way undisrupted from the tank to the carb.

The problem is likely a dirty carburetor.

Continue your troubleshooting based on the results of this initial test.

3. Check if the shut-off valve screen is clogged up

Fuel exits the fuel tank through a shut-off valve at the lowest part of the tank. Inside this valve, a mesh screen is supposed to stop dirt and debris from entering the fuel lines.

Disconnect the fuel line from the valve to see if gas comes through. If fuel does not flow freely, you need to remove the valve to clean it.

All of the fuel left in the tank will drain as you remove the valve. Use a bucket to collect the fuel.

Use carb cleaner, some fresh gas, and a toothbrush to clean the valve and mesh screen. Pour some fresh gas in the tank to flush out any remaining gummed-up old fuel or debris before installing the valve.

If the gas in the tank is old or contaminated, you should not put it back in the tank after cleaning the valve.

4. Check if the fuel filter is clogged up

Not all ATVs have serviceable fuel filters, but some do. Trace the fuel line all the way from the fuel tank to the carburetor. Look for a cylindrical canister unstalled in-line anywhere on the fuel line.

Fuel filters are cheap and easy to replace, so it’s worth doing if you suspect that something disrupts fuel flow.

5. Troubleshoot a fuel pump that is not working

ATVs with traditional carburetors usually have a vacuum-operated fuel pump. They are run by vacuum/pressure pulses created in the crankcase. The negative pressure pulls fuel in, while positive pressure pushes fuel out.

Locate the pump by tracing the line coming from the gas tank.

There are three rubber hoses attached to the pump. One is fuel coming from the gas tank. One is fuel exiting the pump and to the carburetor. One is the pulse-line (air), usually marked with a “P.”

Disconnect the inlet fuel line and position it lower than the fuel tank to make sure gas flows undisrupted from the gas tank.

Reconnect the inlet fuel line.

Inspect the vacuum line for any damage or cracking and replace it if necessary. Leaks will prevent the pump from working correctly.

Make sure the pulse line is connected correctly both at the pump and by the crankcase.

Make sure the engine oil isn’t overfilled. This may cause some oil to get trapped in the pulse-line, obstructing airflow.

Also, inspect the fuel lines going from the fuel tank to the fuel pump. If there are any signs of weather cracking, replace the line. Cracks in the fuel line may cause the pump to suck false air into the tube instead of gas.

If you have a vacuum gauge, connect it to the vacuum. The gauge should follow the pulses. If there is no vacuum, there may be internal problems inside the engine, like a stuck valve. Fixing such issues is usually a job for a mechanic.

If the pump is still not working, you may need to replace it.

Alternatively, you can pull it apart to give it proper cleaning and a rebuild. Inside there are check-valves that may get suck if dirt enters the pump. There is also a rubber diaphragm that may stretch or crack over time.

6. Test a vacuum-operated shut off valve (petcock valve)

Some ATVs have a vacuum-operated shut-off valve that is designed to open only when the engine is running.

Identify the vacuum line that goes to one of the inlet ports. Disconnect the line and draw a vacuum to the disconnected port. The valve should now open and allow fuel to flow.

Inspect the vacuum line to make sure it is correctly connected at both ends and has no cracks that will draw false air.

If you suspect that the valve is not working, put it in “prime” as this will override the vacuum-operated valve. This will tell you if the valve is working or not.

7. Clean the carburetor

Old unstabilized fuel and debris from the gas tank may completely gum up the carburetor or block the jets so that the engine is not getting any fuel.

I recommend using a product like Seafoam or similar to see if it will dissolve the gummed-up fuel before embarking on a more thorough cleanse. Leave the choke wide open to allow maximum flow.

Click this link for instructions: https://seafoamsales.com/uploads/2018/12/HOW2_Gummed-Up-Carburetor.pdf

If Seafoam doesn’t work, your best bet will be to remove and disassemble the carb to clean it properly. This job may not be for everyone. Consider asking a mechanic if disassembling the carb seems intimidating.

Start by draining the carburetor. There should be a drain screw at the bottom of your carb bowl.

Disconnect the carb from the ATV and move it over to a tidy workbench. You do not want to be missing any parts when reassembling the carb.

Disassemble the carb. Take photos as you remove parts to keep track of where things go.

Use carb cleaner and a toothbrush to clean as much as you can.

Use an air compressor with a nozzle to clean all the small passages inside the carb.

Remove both the main jet and the pilot jet. Make sure you can see the light coming through it. If you are not able to clean the jet, it’s best to replace it. Make sure the float assembly is pulling up the float needle and is not stuck.

Reassemble the carb and install it on the ATV.

You will also need to address the cause for your dirty carburetor, or it will clog up the next time you ride. Drain or siphon all of the old fuel out of the gas tank. Flush the tank with some fresh gas. Replace any fuel filters, as well as they are likely just as dirty as the carb.

Consider adding a cleaner product such as “Seafoam” to your first tank of gas after the cleanse. This will dissolve any gummed-up fuel still trapped in the system. Follow the manufacturer’s instructions, depending on which cleaner product you choose to use.

I recommend these links for a more detailed and illustrated guide on how to disassemble and clean a carburetor (external links):

How to disassemble and properly clean a carburetor:

https://www.rockymountainatvmc.com/rm-rider-exchange/clean-carburetor-motorcycle-atv/

Clean a carburetor by using chemical carb cleaner:

When an EFI (electronic fuel injection) ATV is not getting fuel

Fuel-injected engines use an electronic pump to feed pressurized fuel through fuel injectors and into the engine.

Troubleshooting a fuel-injected ATV is a bit trickier than carbureted ATVs, but it’s possible:

1. Make sure the internal fuel filter is not clogged

Most fuel-injected ATVs do not have a serviceable fuel filter.

Instead, they have a non-serviceable screen or a sump-filter located inside the gas tank. Note that some EFI ATVs also have an inline external fuel filter.

The screen or filter is one component of the complete full fuel pump assembly located inside the tank. These filters are not meant to be serviced but may still clog up.

You need to remove the whole fuel pump assembly to access the filter.

Begin by removing any plastic covers to access the top of your gas tank. There you will find a large plastic locking-ring that connects the entire fuel filter assembly to the fuel tank. You may need a set of large pliers to remove the ring as they tend to bind.

Be careful so that you don’t damage any fragile plastic components as you remove the pump assembly.

The filter will be at the very bottom of the assembly. You will generally need to replace the whole assembly to replace the filter.

If you want to save some money, consider looking up a suitable replacement filter on-line.

2. How to troubleshoot an EFI fuel pump

Electric fuel pumps tend to fail for no apparent reason from time to time. Before they break completely, they may be getting weaker gradually due to wear.

A worn fuel pump may not create a high enough fuel pressure for the injection system to mist the fuel properly, which may prevent the ATV from starting. Aftermarket fuel pumps are available for most ATVs, but replacing them is not for everyone.

Also, you have possible fuel pressure regulator issues or bad o-ring seals.

The best way to test an electric fuel pump is by measuring the fuel pressure at the fuel rail. This will, however, require a specialist tool that the average home mechanic does not have.

A clogged fuel filter or clogged fuel lines may cause too low fuel pressure as-well.

Before replacing the fuel pump assembly, it’s worth making sure the bike is charging correctly, as a low voltage will negatively impact fuel pump performance.

3. How to troubleshoot fuel injector problems

Modern EFI ATVs may provide an error code indicating fuel injector issues. Troubleshooting fuel injector problems, however, is a task that often gives even seasoned mechanics a headache. I recommend you save this job for a dealer.

The ATV is not getting a spark

Here are a few things to try out if your ATV is not getting a spark:

Make sure the kill switch is turned “ON.”

Test if the kill switch works by using a multimeter, a test light, or a simple continuity tester. Poke one probe into each of the two cables going into the switch. There should be no continuity when the switch is off and continuity when it is on.

Check for unplugged or damaged wires in the wire harness.

Replace the spark plug; it may be damaged even if it looks ok.

Test the internal resistance of the ignition coil. Use a multimeter to check for internal resistance between the positive and negative terminal. Set the meter to 200. You should get a reading of 0-2 ohm. Over 2 ohms, the coil is likely bad and needs to be replaced.

Test the resistance between the positive terminal of the coil and the spark plug. Set the meter to 200.000. You should get a reading of 10.000 – 25.000 ohms. Any reading outside of this range indicates that you likely have a bad coil.

Finally, check if the stator is working properly. You will find a method for testing the stator in this post.

The ATV won’t start – it just backfires

When you try to start the ATV, the engine seems to crank just as normal. But the engine will not start. All you get is one or several loud bangs coming from the exhaust.

These bangs are known as the ATV backfiring, usually caused by the air/fuel ratio being too rich or too lean.

1. The ATV has become flooded

If you forget to engage the kill switch before trying to start the bike, it will pull gas into the carburetor, but there is no spark to ignite the fuel.

When too much gas enters the carburetor, there won’t be enough space left to mix the required air/fuel ratio for the bike to start and run.

If you have the time, let the bike sit for a couple of hours before trying to start it again.

Alternatively, you can remove the spark plug while turning the engine over for a few seconds. Any excess gas will escape through the spark plug hole. Wipe the plug clean and put it back in. Then try starting the ATV as usual.

2. The spark plug has gone bad

Spark plugs are considered consumables that may need replacing from time to time. A spark plug that has gone bad may prevent the ATV from starting and only cause it to backfire.

Replace the plug with a new one according to the manufacturer’s specifications.

3. The air filter is clogged

A clogged air filter will restrict airflow and, therefore, significantly impact how rich your ATV engine operates. Too little air will cause an overly rich mixture, resulting in symptoms like the ones you experience.

Clean or replace the air filter with a new one before trying to start the bike again.

4. The valve clearance is incorrect

Another possible cause of these symptoms is that your valve clearance is incorrect. As the engine gets some hours to it, the valves may seat deeper in valve seats and may need adjusting.

Checking and adjusting the valve clearance on an ATV is not that hard to learn, but it is recommended that you ask for guidance from someone more experienced the first time you do this job. If you do it incorrectly, you risk causing permanent damage to your engine.

5. The timing is off

Your bike’s timing is what tells the bike when to pull air and fuel into the cylinder, when to ignite the fuel and when to discard exhaust gasses out the exhaust. If one cam is off by just one tooth, you may run into starting issues accompanied by the occasional backfire.

If you’ve been working on or removing some of the timing components, you need to make sure that everything is reassembled correctly. Lookup a timing diagram for your specific ATV and make sure all the timing marks line up.

If the task of aligning the timing marks sounds intimidating, you are probably better off leaving the job to a mechanic.

6. The flywheel timing key is sheared

The timing might be off even if you did not work on any of the timing components. What often happens is that the timing advance key, also known as a rocket key, has sheared and needs replacing.

The timing key plays a crucial role in timing your bike’s ignition as it locks the flywheel in the right position on the crankshaft. If it breaks, your bike’s timing will be off immediately.

This little metal part is designed to break to protect other engine components. From time to time, it may break even if there is nothing else wrong.

Luckily they are not that expensive or time-consuming to replace. It is not a job everyone will be comfortable doing for themselves. Still, nothing an averagely skilled home-mechanic can’t manage after watching a couple of youtube videos for their specific brand and model.

The key is located on the crankshaft. You need to unbolt and remove both the flywheel-cover and flywheel (the flywheel on an ATV is actually called a generator) to access it. A flywheel puller may be required.

If the key is sheared, remove all pieces from the old timing key and install a new one according to factory spec. Ask your dealer to make sure you get the right one. Install the flywheel and flywheel cover before trying to start the bike.

Make sure the timing marks are lined up correctly. The timing mark layout will be different from model to model. Please refer to your service manual.

7. The carburetor has become dirty

A dirty carburetor may prevent enough fuel from getting to the cylinder, causing a lean backfire.

Due to the backfire, you know that at least some fuel is getting through. Please refer to step 3 on how to clean the carb.

8. The fuel is bad or contaminated (water in the gas)

Before spending money on a mechanic, it may be worth draining your gas tank and adding fresh gas. Gas may go bad if it sits too long, or it may get contaminated with water due to condensation.

Most gas tanks will have a removable drain plug or on/off switch at the bottom. Your next best option is to pump or siphon the fuel out of the tank.

9. Tere is low compression

If a valve has stuck open, the compression will be too low, and the bike will not start. Repairing a stuck valve is usually a task for a trained mechanic.

The ATV won’t start – it just buzzes

If all you hear when turning the key is a buzzing sound, it is usually because your battery is dead or needs charging.

The buzzing sound you hear comes from the starter solenoid relay that won’t kick in due to low voltage.

The solution is usually quite simple. Charge the battery or replace it if it is dead.

Also, make sure all of the power wires going from the battery to the solenoid are correctly connected and not corroded. Put a test light across the connection you are testing as you activate the starter.

If the problem is not battery-related, you may have a bad starter or even a seized engine, preventing the starter from engaging. After ruling out a bad battery, it’s recommended to have further troubleshooting done by a mechanic.

The ATV won’t start – it just clicks

When activating the starter, the engine won’t turn. All you can hear is a clicking sound each time you press the starter button. The clicking sound is coming from the starter solenoid.

1. Bad or corroded solenoid

A solenoid that is working correctly will provide an audible click as you activate the starter. But the solenoid may be bad even if it clicks due to internal corrosion.

Use a multimeter to test if the solenoid closes the circuit as you try activating the starter.

Put your multimeter to DC Voltage. The red lead goes to the starter side of the solenoid. The black lead goes to ground. There should be no reading when not pressing the starter button. But when you activate the starter, you should get a voltage reading of 12V or more.

If you don’t, your solenoid is probably bad and needs replacing.

As an alternative method, you can use a piece of cable to jump your solenoid. Make sure the cable you use can handle the high current. If the ATV starts when jumping the solenoid, you know that the solenoid is bad and needs replacing.

2. The starter has gone bad

If your solenoid is good, the problem is likely with the starter. Starters may wear out due to old age, or they may go bad from a busted seal that will allow oil or water to get inside of the starter.

To test the starter, you need to remove it from the ATV. It’s connected with a few bolts. You will also need to remove the cable coming from the solenoid.

Use a fully charged battery and a set of jumper cables to test if the starter will spin as it’s supposed to. First, you should use the positive lead to connect the positive battery terminal with the positive (red) starter cable. Then attach the negative lead to the negative battery terminal.

Hold the starter firmly in place and complete the circuit by connecting the negative lead to where your starter ground to the engine.

The starter engine shaft should start spinning freely with no signs of drag or scraping. Replace the starter if it is bad.

The ATV won’t start after running out of gas

After running your ATV completely dry, you may find that it won’t start even after filling it up with fresh gas.

If it was running fine before you ran it dry, your problem is likely fuel-related as running the bike dry will not cause damage.

1. The fuel pump needs more time

The fuel pump will need some time to suck up fuel after the bike has run completely dry. Fuel-injected ATVs, in particular, can be extra tricky.

Make sure the fuel tank is full.

Turn the key to the on position, leave it for a few seconds before turning it off. Do not try to start it. Repeat this process a few times, which will help prime the fuel lines and fuel filter.

Then try running the starter for several seconds or pulling the starter rope until the bike starts. If the bike doesn’t start after running the starter for about 10 – 15 seconds or pulling the starter rope 15-20 times, you should stop and continue troubleshooting.

2. Use the carburetor primer

Not all ATVs have one, but if yours has a primer pump, you should use it to pump fuel back into the carb manually.

Look for a button on the side of the carb that may look like a choke knob. You will need to pump it several times for it to have any effect.

3. Running the ATV dry have caused dirt to enter the carburetor

Switching to “Reserve” and letting the bike run completely dry may allow dirt and gummed-up fuel that has set on the bottom of your gas tank to be sucked into the carburetor.

The same applies to gas contaminated with water, which is heavier than gasoline and will fall to the tank’s bottom.

Clean the carburetor, as described in step three.

4. Pour some gas in the spark plug holes

Remove the spark plugs and pour a dash of gas into the spark plug holes. Reinstall the plugs and try starting the bike.

This will provide enough fuel so that the ATV starts and begin sucking fuel on its own. You may need to do this 2-3 times before you succeed.

5. Blow air through the gas tank vent

Blowing with a steady pressure into the gas tank vent tube while running the starter may help the fuel to start flowing.

6. Check for a bad spark plug

Running the bike dry won’t harm the spark plug per se, but contaminated fuel may. You may need to replace your spark plug to get going again.

7. The fuel-pump is burnt out

Some ATV fuel pumps cant take being run dry. When run dry, the RPMs will go up, and the pump will burn out due to a lack of cooling and lubrication from the fuel.

Try removing the pump and check for internal resistance with an ohm-meter. If there is no resistance, the pump is likely bad.

The ATV won’t start with starter fluid

First of all, it is not really recommended that you use starter fluid on your ATV in the first place. Starter fluid evaporates very easily, and the vapor is highly flammable. Both you and the ATV can catch fire from a spark caused by a short.

It’s much safer and just as effective to carefully pour or spray some gas straight into the cylinder through the plughole. A couple of ounces should be enough before installing the spark plugs and starting the bike.

As long as the spark plug provides a bright blue spark and fuel is entering the cylinder, you may suspect that your compression is not good enough. Use a compression gauge and check if the bike’s compression matches factory spec. If it doesn’t, the engine might need an overhaul.

If the spark seems weak, the problem may be with the pick-up coil. Look for cracks or any other visible damage. If the coil is damaged, replace it with a new one. Note that the coil may be bad even if you’re getting a spark.

The ATV won’t start after washing

Most ATV manufacturers recommend that you not use a pressure washer to clean your ATV, which may damage electrical components. Instead, it would be best if you washed the ATV by hand using only a garden hose and mild soap.

Here are a few tips to try if your ATV won’t start after washing it:

Washing may have caused grit to enter the kill switch or starter button switch. Open the switch and clean it with an electronics cleaner.

Water trapped inside the spark-plug booth may cause a short that will prevent the ATV from starting. Unplug the boot dry it thoroughly. Using a hairdryer will speed up the process.

Leave the ATV in the sun to dry for a day or two before attempting to start it again.

Open the airbox to drain any water and let the filter dry out.

On a fuel-injected ATV, try spraying the injector with an electronic cleaner to expel any trapped moisture.

Check if any water has entered the fuse box, causing shorts.

Other electronics that don’t like getting wet are the coil pack and CDI/ECU box.

If you washed the bike while it was running, it might have sucked water into the carbs. Locate the drain plug on your carb and drain it. You may also need to replace your spark plug. Just a small amount of water may foul the plug instantly.

If too much water has entered the cylinders from running the bike when washing it, it may have damaged the valves or piston rings.

Disconnect and apply dielectric grease to every electric connector as a preventive measure for future trouble-free washing!

The ATV is flooded and won’t start

I’ve dedicated an entire post on how to repair an ATV that’s been submerged in water.

The ATV won’t start in cold weather

Start by making sure the battery is healthy and fully charged. If the battery is below 12,6V, it needs a charge to provide the necessary cranking power to start a sub-zero ATV.

Make sure the spark plug is healthy.

Clean the carb as described earlier in this post. A dirty carb may cause issues when it’s cold.

A carbureted ATV may need a richer fuel mixture to start in the cold. Usually, it’s enough to turn on the choke, but you may need to install one size bigger pilot jet. Try giving it some gas when turning over the engine.

The intake valves may be tight. Remove the rocker cover and make sure the valve clearance is according to spec.

The ATV won’t start with a new battery

You’ve just installed a new battery, but the ATV still won’t start.

Make sure the battery is fully charged.

Make sure the battery is installed correctly.

Then, refer to the other topics in this post according to how your ATV is behaving. Does the engine turn over? Does it make clicking or buzzing sounds? Start from the top and work your way down if you are not sure where to begin.

The ATV won’t jump start

If you cannot jump-start your ATV, it may not be a dead battery that is causing your starting issues. Make sure you are following the proper procedure for jump-starting an ATV.

The ATV won’t pull start

If the ATV starts with the electric starter, it should start with a pull starter as-well. I recommend that you begin troubleshooting as if the turns over but won’t start.

How To Push Start An Automatic ATV (3 Steps) – Ultimate Off-Roading

Push starting a vehicle is a way of starting an engine if the battery is dead or does not have sufficient charge to turn the starter motor. This method of starting the engine is also known as bump starting or popping the clutch and is usually used for manual transmission vehicles.

Is there a similar method to starting automatic vehicles, specifically your ATV, if the battery is not operating at optimal capacity? Generally, only ATV’s with certain types of automatic transmissions can be push-started safely. If you try to push-start an automatic ATV with the incorrect transmission type, it will at best not start and, at worst, cause damage to the transmission.

If your ATV can be push-started safely, then here are 3 steps to get your ATV started.

Get your ATV to the top of an incline or steep driveway. Put the ATV is gear. Get on the ATV and roll down the hill to gain speed and start the engine.

There may only be three steps to this push-start procedure, but there is more to the three steps than what first glance portrays.

Remember: Before trying any push-start method on your automatic transmission ATV, you need to make sure it is capable of starting using this method and that no damage will be caused by attempting this method!

Push Starting Your Automatic ATV

Many ATV riders will tell you that you cannot push-start an automatic ATV, and in most instances, they are correct. Some automatic transmissions require the parts of the gearbox to be rotating before a gear can be selected, while others rely on the compression of a running engine to engage the clutch.

There are, however, some ATVs that can be started using this method, particularly if they have hydraulic pumps.

Get your ATV to the top of an incline or steep driveway. The goal here is to get some elevation so that you can get sufficient momentum as you roll the ATV down the hill. The incline that you use as a starting point will, therefore, need to be high enough and have a steep enough angle to achieve this purpose. Put the ATV in gear. At the top of the hill, climb aboard the ATV and put it in gear before launching yourself from the crest of the hill. Roll the ATV downhill. This is where it is useful to have a second person to give you a boost to help get you started. Get your assistant to give you a running push to start you on your downward trajectory. Once you have gained sufficient speed and momentum, the engine should turn over and fire, starting the ATV.

This process can be an exhausting undertaking if you are doing is all using man-power. Pushing an ATV up a hill may require what some would consider superhero-type strength! After pushing your ATV to the top of a hill two or three times, you will begin to wonder why you started off-roading on your ATV to begin with!

The physical effort required to perform this task repeatedly may prompt you to employ another method to gain the necessary momentum to start the ATV. You may try towing your ATV with another ATV or behind a truck.

This is, however, a potentially hazardous way to try and start your ATV, and you should weigh up the risks to determine if it is really worth it.

If you struggle to push-start your ATV or your transmission does not allow for this starting method to be used, you may want to try one of these other methods to get your ATV fired up!

Can I Start My ATV With Jump Cables?

Another method commonly used to start vehicles with battery problems is to use jumper cables from one vehicle’s battery to another.

The idea behind the jumper cable method is that the vehicle with a battery that is in good working order will supply a charge to the problematic battery. This charge should be enough to allow the engine to be started.

This is a well-known and widely used method in vehicles that are of the same type but requires some care when you are attempting this method with vehicles that are different.

For example, using another ATV to connect to your ATV battery is a safe method. Make sure the batteries are connected positive to positive and negative to negative. Start the donor ATV and wait a few minutes while it delivers charge to the ailing ATV. It sometimes helps to keep the revs slightly elevated on the ATV that is doing the charging. After a few minutes, try starting the ATV normally with the leads connected and the second ATV running.

If the ATV is still struggling to start, you may want to try and let it charge a bit longer before trying to start it again.

A second example is using a car or truck to provide the charge, and this is where some additional care needs to be exercised due to the differences between the two vehicles.

When using a car as the charging vehicle, you can connect the cables to the battery as normal, but leave the car turned off. Do not switch on the ignition or start the car as the differences in the electrical systems may cause damage to your ATV or the car.

With the batteries connected, wait a couple of minutes for a charge to build up in the ATV battery and then try to start the engine of the ATV. Hopefully, you should be able to get your ATV running after a couple of attempts.

Will My ATV Start If The Battery is Dead?

If your ATV battery is completely dead in that it does not even power the ignition lights to some degree, then the problem of starting your ATV takes on a different dimension.

With a completely dead battery, it may be possible to get the engine started using the push-start or bump-start method, but the battery may not hold the charge. If your battery is in this condition, it will not be able to successfully store a large enough charge to start the engine after the ATV has been switched off.

If you are using the cable start method, you may fail to get the ATV to start at all. This is because this method depends on the good battery being able to charge up the flat battery to the point that it can start the engine. If the flat battery is faulty and unable to hold a charge, then this method may not work to get the ATV started.

If your battery is in this condition, the only solution is to replace the battery with a new one. This should solve much of your ATV starting problems.

Are There Other Ways To Start Your ATV?

If the battery is the cause of your starting problems on your ATV and the methods already mentioned are not achieving any success for you, then you may wonder if there are any other options.

Unfortunately, due to the simplicity of the way the battery system works, there are not many different ways to achieve a current flowing in the circuit. Your only other option may be to take your ATV to a mechanic for a professional diagnostic to be run to establish the problem.

Some methods are purported to work, such as connecting a drill with an impact socket to the flywheel nut and running the drill in reverse. If the ATV is in neutral, the ignition is on, and the kill switch is in the on position, the drill can turn the flywheel sufficiently to induce a current in the coil enough to provide a spark.

This method may seem easy, but it lacks some practicality, as it only works on smaller engines and requires you to have a drill and impact socket on hand at the time your ATV won’t start!

Conclusion

Starting issues caused by battery problems are notorious for appearing at the most inconvenient times, such as when you have no tools at hand or a fellow off-roader to help you out. This should not be looked at as a downside to the activity, but rather as a part of the adventure that is ATV off-roading!

Choose to learn from the experience so that you are better prepared the next time the problem occurs, or you are in a position to help another off-roader who suffers from the predicament!

Happy ATV’ing!
