I have a 95 GMC with th 5.7L TBI. When you re-start the truck hot, it will start them innediatly die. Crank the starter for a while and it will re-start with an erratic idle and then smooth out in about 10 seconds. It only does this after sitting hot for 20 or 30 minutes after stopping the engine. Cold start, no problem. Turn truck off and re-start in 10 minutes, no problem.
help :(
