Having problems with your 1994 GMC Safari ?
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.
Check the fuel pressure. I had the same issue with my GMC, and changed the pump. Now, it runs great
Have the computer checked or inspect fuel injecters if all else fails fuel pump weak.
