I appreciate all your answers. It makes sense that it’s electric based. This is what I’ve struggled with on this rig since I got it. I recently “fixed” the oil pressure gauge because the wiring to the oil pressure sender unit was held in place by threads. However, I may have gotten this wrong as there was only one cable available to connect to and two places to connect to the transmitter unit. Whatever I did may have gotten the gauge working again, but the fuel control relay broke. This is the most likely scenario. The other thing I fixed a few days ago was the alternator. The PO had severed the cable from the alternator to the battery and shrunk it open at the end. So I ran it to the battery and now it’s charging again. The EDIC started responding a while ago… irregular clicking when first turning the key. I took it out and looked at it…didn’t see anything wrong and put it back on…what has sort of fixed it so far is cut.1tontoy yes oil level is ok and recently changed. I thought Sandcruiser too at first, but it starts right up again, I put new hose clamps on all the rubber-metal connections and I can’t see any air when bleeding, so I’ll rule that out for now. Tourboy, more info about that? That sounds like a good way to go if not solved by some electrical CSI work. Thanks again everyone for your help. UPDATE: So with further searching I found an answer from lostmarbles that was about the EDIC. While “fixing” my oil pressure sender unit, I reconnected the disconnected wire that came from the low oil pressure sender unit. I’ll see if disconnecting this cable solves my problems and then try to figure out how to get it to work instead of just disconnecting it. From what I’ve read here, it seems like this won’t be the last time the EDIC has me scratching my head.
11 Causes of a Car Losing Power While Driving Up Hills

When you drive a car, your engine and all other components have to work extra hard when going up an incline or hill. You must have enough power to accelerate a vehicle anywhere, especially on a hill where gravity works against it.
If the vehicle contains faulty components, this can make it difficult for the engine to push the vehicle up the hill when accelerating. There are so many reasons why this could happen, so you need to pay attention to the different causes and possibilities for it.

Reasons why your car loses power when going uphill
1) Bad fuel filter
You cannot have a well-functioning engine without fresh, pure gasoline flowing into it at all times. Failure to have a good fuel filter to prevent the fuel’s impurities from flowing into the engine can ultimately compromise your engine’s performance.
Fuel filters usually have a service interval when they need to be changed. If the fuel filter is not changed for a long time, particles and sediment from the gas tank will eventually accumulate and clog the filter, restricting fuel flow.
If fuel flow is restricted too much, not enough fuel can reach the injectors and the car will likely run lean.
2) Clogged exhaust filters
The catalytic converter and the silencer serve as filters for the exhaust pipe, for pollutant emissions and noise. The muffler reduces exhaust noise and the catalytic converter reduces exhaust pollution.
When one of these filters becomes clogged, it limits the engine’s power and ability to accelerate. You may be able to drive slowly on flat roads, but once you come to an uphill road, you probably won’t be going anywhere quickly.
A clogged exhaust pipe can be dangerous, as in extreme cases it poses a fire hazard. If you think your exhaust may be clogged, the problem should be addressed as soon as possible. Depending on what’s wrong, you might be able to delete it yourself.
3) Clogged air filter
As much as the internal combustion chamber needs clean fuel, it also needs clean air to be mixed with it to keep the engine performing efficiently.
If you have a clogged air filter that cannot prevent contaminants such as dirt and bugs from entering the internal combustion chamber, these contaminants can damage the engine.
It is important to have a clean air filter that is not clogged so that air can continue to flow through the filter and enter the chamber without the contaminants it contains. Otherwise the engine will never be strong enough to get up a hill.
4) vacuum leak
Vacuum leaks often only affect vehicles that are idling, but if the leak is bad enough it can affect the vehicle’s overall performance. A vacuum leak can be tested with a smoke test to ensure the air intake system is tight as it should be. A vacuum leak will cause the vehicle to run lean if unmetered air enters the intake manifold.
5) Clogged injectors
Fuel injectors are the final parts before the combustion chamber in a long list of components that make up the fuel system.
Injectors tend to last a long time, but they can clog with age or poor fuel quality because the fuel filter doesn’t collect all the deposits from the gas tank. When an injector becomes clogged, it affects the spray pattern and the injector’s ability to atomize fuel.
If the injector becomes completely clogged or inoperable, fuel will not enter the combustion chamber and no power will be produced on that combustion stroke.
6) Bad fuel pump
If the fuel pump is on its way out, it may not work intermittently or at all. A symptom of the car being fuel starved is a car that runs correctly at idle and at low loads, but falls flat on its face when you ask for more power (e.g. when going uphill).
Fuel pumps can fail due to age, deposits, or improper fuel. If you often drive around with an almost empty tank of gas, you might want to reconsider this habit. Fuel is used to cool the fuel pump and running it on less than a quarter of the tank for any length of time can significantly reduce fuel pump life.
7) Bad spark plugs
As your spark plugs age, the spark gap can increase as the center and ground electrode(s) wear. If that gap gets too big, the spark may not always be able to jump across the gap.
No spark means no combustion in that cylinder, causing misfire. This is a wasted combustion cycle that produces no electricity.
8) Bad ignition coils or ignition wires
Ignition coils and spark plug leads convert the low voltage power from the battery to the high voltage required to bridge the spark plug gap. As ignition coils and leads wear, they can lose insulation and short out. In this case, it may happen that the spark plugs are not supplied with sufficient voltage, which will lead to misfires.
9) Faulty camshaft position sensor
The camshaft sensor calculates the camshaft speed and transmits this information to the electronic control unit. This allows the engine control unit to properly manage the ignition timing and fuel injection timing.
But if you had a faulty camshaft position sensor, the timing on those two would be wrong. This would severely limit the engine’s performance and certainly make it more difficult to drive the vehicle uphill.
10) Low cylinder compression
High cylinder compression is crucial to give the engine enough power to propel the vehicle uphill. Once you start feeling low cylinder compression, your vehicle will always have trouble going up hills because the engine power isn’t strong enough to get it up there.
11) Environmental Conditions
If it is very hot outside, your vehicle will have higher intake air temperatures. Higher intake air temperatures make the engine more susceptible to knocking. When the engine knocks, the computer has to remove the ignition timing, which reduces power and makes combustion a little safer for the engine components.
They’re also probably running the air conditioning, which makes the engine work a little harder.
When you’re driving at very high altitude, less air needs to be drawn into the engine. Less air means the computer has to inject less fuel to maintain the correct air/fuel ratio, so the car doesn’t make as much power.
Altitude affects turbocharged vehicles much less than naturally aspirated and supercharged vehicles. In a turbocharged vehicle, the boost pressure is increased until the target boost pressure is reached. For other intake types, the intake pressure is based on mechanical limitations and cannot be adjusted by the engine computer.
things to remember
If you experience acceleration problems when attempting to go uphill, do not put your foot on the accelerator to try to get up the hill. You will only put more stress on the engine, which is of no use if there is a problem somewhere in the engine.
The best thing you can do is avoid driving on steep grades just until you can get to an auto repair shop. However, as these problems worsen, even driving on flat roads will eventually become a challenge.
It all depends on how long you let the problem persist.
