Question about 2001 GMC Sonoma Extended Cab
We replaced the fuel pump in a 2001 gmc Sonoma 6cyl and the truck will not start now. We knew the fuel pump was bad because you would need to bang the tank to get it to kick in, then it just quit. We took the tank down, replaced the pump and reinstalled the tank and did all the correct wiring. The pump will whirl when the key is turned to the on position, the truck will crank,but it will not fire. It sputters slightly but will not start.Is there a step we aremissing? Priming the lines? An electrical issue perhaps. We had the battery disconnected. Will that trigger some reset that we need to do? Thanks
Check to see if you removed the fuel pump solenoid, which is one of the steps you should have done when changing the pump.

Check your fuel lines, make sure supply line is connected to fuel pump outlet,and the return line is connected to the return pipe on tank.
I did hook them up backwards (I KNOW) when i tried to start the car i heard the pump but car wouldn't start (no fuelgetting to engine) checked lines and changed them to correct locations , car started right up
I hope this helps
