FUEL PUMP

2006 Chevrolet Impala • 120,000 miles

Fuel pump will not prime, replaced fuel pump and still wil not prime, all fuses and relay is good, relay clicks and is working, is there something that is telling the fuel pump to not kick on? Was driving fine and parked it, went to start it and wont start just turns over.

Follow the gray wire back to see if it's getting power or a bad connection

Followed it back and no power, ran a new wire back from the fuse box and fuel pump is working?

Then the problem lies in the electrical box where relay is either a corroded terminals or just plain bad connection.

I completly took the box apart took apart the relay, traced the wire all the way back to the pump, not athing wrong, I ran a new wire from the fuse that the relay controls to the fuel pump harness and eliminated the previous gray wire, everything works fine now, so I'm going to make it permanent.
