Chevrolet Repair: 1997 chevy s10 fuel pump problem, chevy s10, spark plug wire

Question
My granddaughter has had her truck stop and be towed twice. The fuel pump was changed last week. Last night we received a call that it had quit on her again. The battery is fine. This truck has had the fuel pump changed once before. Any other suggestions as to why it just quits? AAA towed it to our garage last night and at first it would not start, then tried an hour later and it started up, then it quit again.

Answer
HI JOE,WELL FIRST THINGS FIRTS,DO YOU KNOW HOW TO CK FOR SPARK AND FUEL ??? WE NEED TO FIND OUT WHEN THIS ENG STOPS IS IT BECAUSE OF FUEL OR IGNITION...WHEN IT STOPS,CK FOR FUEL AT THE CK PORT ON THE FUEL LINE, BY THE [THROTTLE BODY]CRANK THE ENG OVER AND PUSH DOWN ON THE SHRADER VALVE AND SEE IF ANY GAS IS COMING OUT. YOU WANT TO SEE FUEL THE ENTIRE TIME THE ENG IS CRANKING OVER NOT JUST ON FIRST CRANK,THIS IS RESIDUAL PRESSURE..IF THERE IS FUEL CK FOR SPARK AT A SPARK PLUG WIRE..I HAVE SEEN MANY BAD COILS ON THESE ENGS.. LET ME KNOW WHAT YOU FIND,THIS WILL GO THE MY CELL SO I SHOULD GET IT FAST.. TOM..
