I bought this truck and drove ity 4 times and then it stopped running. I found the fuel pump fuse blown. I replace the fuse and it blew again. I pulled the tank down removed the fuel pumpo, and intallaed a new 450.00 pump. Truck ran for about 10 min. I left it running ran into my garage, came back and found the truck stalled. I tried to start again no go. The fuse is not blown what can it be?

I suppose there is no code(s) if there is please let me know.
I suspect the regulator in the throttle body.

Sending the pic in your email.

The weird thing is I pulled down the tank and reinstalled the tank after changing the pump. Everything worked then all of a sudden the regulator goes? I'll check and let you know.

Have you checked fuel pressure with a gauge, is the pump working? Are your fuel lines blocked (supply&return)? Suggest blowing them out. Blow back into tank to clear anything from the pickup. If the pump is not working check for power and earth at the pump.
