Fuel pump problems


Asked by Sep 01, 2016 at 02:35 PM about the 2002 GMC Sierra 1500

Question type: Maintenance & Repair

changing fuel pump and the new one will not work. Put the old one back and it
will not work either. It was working before and really just needed the new little
filters, so that is why I got a new pump. I have voltage to the pump wire. 12 V
when you turn the key on, but the pump does nothing--either of them.
