Question about 1998 GMC Sierra
I have a 1998 GMC Sierra 1500 Vortec 4.3L, etc. I had to replace the fuel pump a while back (changed filter also, etc), drove fine for a week and then went out again. Replaced the fuel pump once again and drove fine for a week or so and then it would it suddenly started stalling after driving for a few minutes. I had to let it sit for about 15-20 minutes and then it would start finally, but once again only allowed me to drive a few minutes and the it would repeat. Problem started about 50 miles from home so it took me about 4 or 5 stalls, wait, start, go, stalls, etc before i made it home. How did you finally correct your problem?
Thanks for your help I will continue checking this since I have like 2 month with this problem, I will let you know what happends probabliy I will need to take my truck to a dealer,

Possibly faulty ignition module is the problem, stalls when engine is hot when you sit for a while it cools off and runs again until it heats up again, those are usually the symptoms of a bad ignition module and after a while it may give out all together and not run at all, usually if the module is at fault it shuts down the fuel pump so the engine don't load up with fuel, do to when engine continuously cranks over the injectors never stop squirting fuel and flood the engine do to lack of spark which is produced by the module, this could possibly be your problem.
