Question about 2000 Chevrolet Express Cargo
Hi, It is most likely either your fuel pump or one of your injectors. Your fuel pump has a check ball in it to hold pressure on the fuel rail. If the check ball quits sealing it lets the pressure bleed off the fuel rail. Same thing if you have an injector stuck open. By turning the key on but waiting to crank it over your letting the fuel rail pressurize again. We just did a 2004 that had the exact same trouble. The pump isn't cheap so you might ask a dealer if there's a way to check to see if it's an injector causing it before you replace the pump. There is a test port on the fuel rail near the throttle body. A mechanic can hook a pressure gauge up and see if that's what's actually happening.
