Question about GMC Jimmy

1 Answer

I posted this problem once but left something out. I inserted it in all caps below. I have a 94 GMC Jimmy 4.3 Vortec and when I crank it it runs for about 5 seconds then turns shuts off. I've changed the fuel filter, the fuel pump , spark plugs and coil. The problem was that it would'nt turn over as if it was out of gas at first. Once I changed the fuel pump it would turn over but would not start. Did the plugs and it started but died after about 5 seconds. But when I changed the plugs I noticed one was soaked with gas so I cranked it with the plugs out and all the injectors were spraying except for one. ONE WAS JUST POURING OUT GAS INSTEAD OF SPRAYING. I'm thinking it's the regulator because it should at least run with 5 injectors. Solutions

Hello chat1999: My name is Roger and I will help. If you have 5 injectors spraying fuel and one that is spaying a steam. You need to replace the one that is not spraying. The engine needs a preset fuel pressure in order to start. The one that is spraying a stream is open and the fuel pressure will never come up to what is required to start and run the engine. I would also look at the oil. If the injector is dumping fuel a lot of unburnt fuel will end up in the oil pan. Also the converter will feel the brunt of the bad injector. This will cause emission problems until all the fuel is burnt out of the system. You think the regulator is the problem. This is simple to check. Unplug the regulator and turn the key on. If fuel is observed coming from the regulator it is defective and should be replaced. Should you need further help please just ask. Please rate the answer. This way I know it was helpful. Thank You for using Fix Ya. Roger

I have a 1994 GMC Jimmy 4.3 vortec 4x4 automatic, and the transmission started to slip, then the battery died, we got it home and it wouldn't start, so we charged the battery and it ran fine for abou


You may potentially have an serious electrical drain in your car circuits. The drain is slow and continuous, draining your battery charge even if you do a start. Check the cabling and look for load on your battery with a Volt meter to check for any charge drainage. Check this as a precaution before replacing any more parts.

My 94 GMC Jimmy 4x4 vortec, is hard to start, cuts off when i make stops, have to put it in neutral when i am at lights and still have to give it gas then. already changed the distributor cap and rotor...


I recently had similar symptoms from my Kia Rio, hard to start, bad idle in gear, etc.
Ended up being the idle air control valve, you can try cleaning yours with carb cleaner and see if there's any difference.
A clogged fuel filter can produce the same symptoms too, that might be the easiest thing to start with, then it's just a process of elimination from there.

IS THEIR WATER IN THE OIL? CHECK THE PLUGS TO SEE IF THEIR WET.YOU MIGHT PUT SOME PLUGS IN IT IF WET TO SEE IF IT WILL RUN.THEN PUT SOME HEADGASKETS ON IT.BUT IN REALITY NEW MOTOR WOULD BE BEST.

Hard start when cold/first start in morning


The pressure relief valve is in the spider fuel injector not the fuel pump. We have had our 94 gmc jimmy for 4 years & have had to replace the fuel injector 4 times which cost right at $500 each time for the part. Yes the spider fuel injector cost averages around $500.
