Question about 1994 GMC Safari

2 Answers

1994 Safari Was running fine til last fill up then began stalling out and idling rough. Changed fuel filter, plugs and gas additive thinking it might be some water in tank. Even drained tank and added new fuel. Hasn't helped and is getting worse. It is AWD XT version with 226k but put in remanufactured engine about 60k ago.

    Your problem may well be the fuel pump. I had the same symptoms on my 2002 Safari and when I changed the pump, it runs great.

Car starts hard then idles roughly for 2-3min then stalls and dies


It sounds like some thing you have done if the fault started after the tune , did you check the gap on the new plugs, check the firing order as it may be messed up . 4 cylinder 1342 6 cylinder 153624 in direction of rotation.

Hello i have a 1995 buick park avenue that has a rough idle and stalls in the mornings after sitting over night the first two or three times it will stall but after that it idles rough til it gets warm,ok...


Try plug wires, that's about all you haven't replaced. Actually if you have an ohm meter you can test them - anything over 6k ohms per foot - REPLACE them. Also run a good fuel system cleaner through it and stay away from cheap gas.

Idles okay, runs rough when gas applied


Either a bad MAP sensor, or TPS. What is the code for the check engine light? This will most likely tell you what it is.

I have a 1994 gmc safari.It seems to have a smooth idle at times


Im not sure if you got it fixed yet! It could possibly be idle air control valve. But here some more suggestions! I had a 94 Safari van 4.3 liter I was working on for about three days and I finally figured out what was wrong with it. It would run fine for a couple minutes and as soon as I hit the gas and let off it would surge, but anyways I ended up changing the distributer, after the fuel pump and filter, mass air flow sensor, egr valve, idle air control valve, map sensor, and ignition module. So that might sove the problem if you were on the same track with it as I was. Hope this helps ya!

94 GMC SAFARI IDLE FAST RUN FINE BUT WHEN DRIVE IF YOU PUSH GAS SLOWLY DRIVE FINE ; IF YOU FLOOR IT ] IT STALLS


First thing to check is the fuel filter. It is likely getting clogged and starving the engine for fuel under heavy load.

ya these motors need tons of fuel pressure so if you have a pressure tester test the fuel pressure prior to the fuel filter and see if it is atleast 25 psi if not replace pump with new or rebuild all the luck to you with current project
