I replaced the fuel pump, filter and fuel pump relay on my tahoe and if I prime the intake with fuel it starts and runs until that fuel runs out. The fitting in the line to the intake to hook a manual guage to has no pressure, I can here the pump come on for just a couple seconds and then it doesnt come on any more? Help

With key on engine off you hear pump coming on
you should have fuel pressure if not suspect bad fuel pump or supply lines
check fuel filter too
