Question about Chevrolet G20

1 Answer

I have a chevy 350 in a 1999 express van. the van has been sitting for 2 years.. The van would not start.. I replaced the battery the van started right up and ran for about 1 hour. then it stalled like someone shut off. Then wouldnt start back up. I replaced the computor, it had started after that but will only run for about 2 sec.s then shuts off like your turning the key off. when it starts and you give it a little gas is acts like its backfireing thru the intake?? any suggestions??

HARD TO START LIKE NOT GETTING FUEL


The van will start fine for periods of 2 - 3 weeks then will turn over & won't start. Usually within the next day or two it will start & run fine
& the cycle repeats. This has been going on since Jan. I've had it towed 5 times, looked at by 2 different mechanics & a chev dealership
mechanic. Still nobody has a clue whats going on. The van has 94,000
miles & besides this problem runs fine. I've had it for almost 7 years
without any other problems. This is beyond the point of being frustrating. I use the van for my business & its embarrasing when
I have to get it towed from a customers house. If anyone has any
ideas it would be greatly appreciated. Thank You, Bob
