I did get the problem fixed. I replaced the head gaskets, intake manifold gaskets obviously, crank position sensor, cam position sensor, plugs, wires, rotor, and dist. cap. The problem ended up being that I had it out of time. There are "veins" that run through the dist. cap, and I had it aligned incorrectly. Also, I did NOT send my heads out to have them pressure tested or anything like that. One thing to keep in mind, if you had any kind of coolant in the oil, you need to change the oil pump. I have good oil pressure upon initial startup, but once it warms up a little bit, pressure drops to almost nothing. I am in the process of replacing the oil pump, but I have to do it in my spare time, if there really is such a thing as spare time. Mine is a 4x4 and I have to pull the front differential in order to get the pan out. SUCKS!!!!

I have a 95 jimmy it starts fine but after it runs for a lil bit stats to act up and if i drive it it really acts up between 1500 and 2500 rpm. I've replaced the Distributor and the cap new plugs and wires changed out the mass air flow i even tried and different computer i replaced the fuel pump a few years back really not sure what to try next so any suggestions would be appreciated

I too face a similar situation with my jimmy 95 model. After a few miles ride, the rpm goes high during idle. Par year I changed the fuel pump and hence I face this issue. Appreciate any suggestions.

I have a 92 jimmy that was running(being driven and died). We replaced the fuel pump. Now it tries to start or sometimes starts and runs for about a minute then dies. Can someone help with suggestions? Thanks for the help.
#303 of 311 1996 Start, run for 5-15 seconds die and then run.

My 1996 GMC Jimmy 4wd 4.3 SLS has had a consistent issue with starting and stalling. It will start, run for a few seconds then die. Then start back up (I wait til I can hear the relay in the glove box click) and usually run perfectly fine until shut off again. Sometimes it will stall 2-3 times but in the end runs just fine. Once going it has zero issues, Can put it to the floor and go with no hesitation or shudder. Can drive for hours again with zero issues, however if driven for any amount of time, then shut off for more than a few minuets you get the same problem with the starting and stalling. I've replaced a bunch of sensors and the Fuel filter. Cam, Crank sensors, PCV, Mass Airflow, distributor cap and rotor and spark plugs have all been replaced. No codes are being thrown and the only engine "problem" is a emissions code thrown from a vent valve in the gas tank. Wondering what else is left at this point. Alternator is next on the list (lights noticeably flicker at night until it's been running for a while) So maybe a voltage thing. Anyways any insight would be great as I'm out of ideas. Fuel pump kicks on every time as well. No vacuum leaks, and when it stalls it sounds like a puff of air coming out of the engine (though that could be the fan slowing down for all I know)
#305 of 311 98 GMC JIMMY Died and wont rerstart

My girl friend was driving the jimmy home and said it the engine just died at a stop sign but the truck still had power, then when she went to restart it it turns over but wont start.
Went and looked at it there is spark when you go to staret it and it seems like the fuel pump is working.
#307 of 311 98 GMC Jimmy losing power
Sep 09, 2013 (2:19 pm)
I can drive the Jimmy about 75-100 miles without any problems and then it loses power and I cannot get it over 20mph. If I let it set for 5-10 minutes along the side of the rode, it starts up fine and I am back at regular cruising speed. I can usually tell when it is going to happen as the rpm's are running high around 3000-3500 for driving around 65-75 mph (speed limit is 75), when it is usually around 2500 rpm's. I did replace the fuel filter and a hose with a slight leak, but it happened again this last weekend.
