2000 GMC C1500 V8 Two Wheel Drive Automatic 145000 miles
Changed my fuel pump last year thinking it was causing my truck to miss intermittently. Bought a Delphi pump. Has been working great up until a few weeks ago. Tried to leave my work, and no start. Towed to dealer and truck started. They checked everything and stated they could not find anything wrong. I picked up truck drove home and again the truck would not start. Has 0 fuel pressure when this happens. I can let it sit sometimes and cycle the key on and off then the pump will come on and it starts and runs fine. The pump seems to not want to "start-up" after its warm. Once the truck is running it will stay running. Only when I turn off the truck does this happen. It happens intermittently and you don't know when. Where do I start? Have check all fuses and swapped relays, replaced oil sending unit, buffed and cleaned all ground wires.
have the same problem?
