Have you access to a OBD II scan tool? From the sounds of it it can be 1 of 4 things. #1Oil pressure is low.#2 fuel pressure regulator is defective.#3 Camshaft sensor does not have synchronization.#4 which would be the least likely given the info you have provided would be a defective ignition module. It should not be the crank position sensor, because if it were the cps it would not start back up.

I have a 1993 gmc jimmy and on the 17th it started to act up by sputtering when we went anything over 30 MPH. We then changed the fuel filter that did not work. So we changed the fuel pump that did not work. We changed the fuel pump relay and that did not work either. What else could make it do that? We checked the spark plugs they are good. Our jimmy won't even start without ether but once we get it to start it will run till about 30 and spuuters again if we turn it off itndoes not start again.

pressure regulator will cause the pump to lose pressure, so will an after market pump. also the weather pack connector that gives power and ground to the pump should be inspected to ensure the pins are not pushed back in and are making good contact. if you get a pump from dealer it comes with the plug included. if not it can be ordered separate. That plug is notorious for going bad

I had two problems that caused mine to not start and i did fix them one was the fuel pump worked when it felt like it and i changed it out and the other one was that the distributor jumped a tooth out because the hold down bolt was striped out and the mech at the auto place kept missing it so i pulled it out to see if the distributor was shorting out and when i put it back in i noticed it was off a tooth so i reset it and tapped out the bolt hole and put a new bolt in. now it runs like it did when it was new.
#110 of 113 98 GMC Jimmy 2dr Fuel pump issue
Jun 10, 2012 (8:08 pm)
I am not sure what the problem is here. gone through 4 pumps in the last month. the last time it failed was at a stop sign and it just died when I went to push on the gas. before when this happened it would sputter and then just die and I would have to let it coast on the side of the road. The first time my pump went out I replaced the fuel filter before installing the new pump....That was back in July of '11 now I am having this issue with the pump. I have purchased my pumps from 1aauto.com instead of advance or auto zone cause they want like 300 bucks for one...
the truck has 143K miles on it. I have checked the pump relay switch, there is gas getting into the filter but there just isn't enough pressure or something I dunno....I have replaced the spark plugs, the wires, the rotor button, distributor cap, battery but haven't replaced the alternator but that was replaced back in somewhere between 03 and 05...not sure what else to check or just break down and get the expensive fuel pump and hope to god it was just I was buying a crappy pump.
if ANYONE has ANY suggestions or solutions because they have had the same problem please let me know I do NOT want to have to buy a newer vehicle if I can spend 300 instead of 3000 for something as simple as a fuel pump or a switch or something
#111 of 113 96 GMC Jimmy fuel leak
Nov 04, 2012 (7:43 pm)
I have A 96 GMC Jimmy with the SCPFI. It has a new fuel pump, fuel filter, and fuel tank vent valve. It does not do this all the time, It will have a "dead miss" at different rpms, but only when it is not under a heavy load( when holding a cruising speed on level ground). If you punch it, it will run fine but when it levels, off again it will usually start the miss again. Yesterday it did it again and got so bad that I pulled off the side of the road. When I got out and walked around the back of the jimmy, I saw that it was pouring gas out from just to the rear of the rear sway bar. After I shut it off, I loosened the fuel cap and it did not leak again when I started it back up. When it cuts out, I can sometimes get it to clear up by flooring it up to redline a couple of times. I can always smell stale gas when I do this. Anyone have suggestions.

you have to use AC DELCO spark plugs and get the distributor cap with brass fittings from NAPA. trust me on this
