Hello everyone,,
First time GMC owner here. Truck just started to have intermittent starting problems. The pump works and it starts other times the pump wont run and obviously wont start. If I hit the tank, the pump https://19216801.onl/ https://routerlogin.uno/https://192168ll.link/ kicks in. Question is, do these trucks have electrical issues I should look for first, before the replacing the mechanical pump?
Thanks.

I would say if it starts when you smack the tank,,,, you need a new pump. As afar as I know the only electrical connection involoved there is up on top of the tank so you'd have to drop the tank anyway to check it out, and if you're going that far just replace the pump.
