hello,
I replaced my fuel pump about 2 months ago it ran fine just till about a week ago i was driving then my truck just cut off on me what is this caused from im not hearing my fuel pump click any other diags would be appricated

 

Have you checked the fuses? If you have a meter you can check for power at the fuel tank connection and if you have none work your way back from there to see where you lose it.

 

What engine do you have? What year truck? What model? That will determine what style fuel pump or pumps you have and how they are hooked up, unless you have added something aftermarket. Then we can help you figure out what possibly can be wrong.

 

ok i have yes there all good i have a 1999 f150 v8 5.4 its just a basic fuel pump nothing speacil

 

Wrong year forum. You have electric in tank high pressure pumps or pump. That's a lot different from most of these trucks, which have mechanical pumps or low pressure electric pumps in the tanks.

 

Moved to proper forum

 

Ck fuel press at rail .Have you cked for codes ? you need to ck fuel press first . Then go from there . If no pressure ck for power and ground to pump. If pressure at rail look for other cause for no start .

 

ok thanks i dropped my tank like i said im not getting power to my fuel pump

 

Ck fuses , Inerta switch , Relay . try switching fuel pump relay with another relay . A wiring diag would be good to help you trace it down . could be in the harness even . You said no power , how did you test ? Good ground to pump ? Just asking .

 

yeah last time i checked im not sure if i should go to a fuel pump
