Re: 2000 chevy express 3500 van with a 350. Hard time...
Sounds like the check valve in fuel pump is allowing fuel to drain back out of lines. this would require ystem to prime up each time it is cranked. check fuel pressure it should hold with key off if it leaks down this is problem and pump will need to be replaced
