I have a 2000 Chevy Express 3500 5.7 gas. A new fuel pump was installed yesterday(5/3/2007). All electricals check out and there is always voltage to the pump when the ignition is on. The new pump will run for up to an hour, but then quits running, even though there is still voltage to the pump. What could be the problem?
Thank you in advance for your help.
