Stalling 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?

check fuel filter remove and shake it and dump out contents on clean sidewalk to see debris thats been going threw it. other test would be fuel pressure . and common fails are fuel pump or crank sensor, try going to your local auto parts store like O reilly they usually have the best code scanners and it's free

sounds like your fuel pump, should be 50-55psi fuel pressure, if you don't have a gage,you could check the schrader valve on the rail with screw driver,watch out if it's pressurized it could squirt in your eye's if it shoot's out really strong,chances are it's working, but if it just does little squirt or dribble, then check it out electrically, fuse,relay etc:before you drop the tank, or like some people do take box bolts out and lift box back and it's easier to change pump then.good luck and any other questions feel free to ask me

I would lean towards the fuel pump, but... How dirty was the old filter??? if it was bad then the new one may have picked up whatever was left in the line. I guess I would go the easy route, replace the fuel filter, this time with the filter off crank the truck and catch the fuel in a mason jar til it is clean, you may need to drain the tank and try to clean it out if it is real dirty. Hope this helped Tim

Need to verify fuel pressure while driving under acceleration. Should stay between 9-13 psi.

yes indeed it is going to! but first check the fuel filter for blockage

I would check to see if the injectors are firing. Most injectors are a pulsing ground type. So you can use a test light to check them.

had this problem on my neighbors 98 chevy truck with the same engine !!
it turnd out too be the fuel pressure regulator,you have too pull the upper intake too replace it!!

sounds like a restriction some where in your fuel system example dirt or anything that might get in your system check your filter and look for contamiation or possilbly a airation problem
