What do i have to do to straight wire fuel pump
Replaced fuel pump in tank also fuel pump
relay switch and still have problems. It will
run sometimes and won't the next time
Have you checked the inertia switch? Fords are known to burn the contacts right at the switch, might be worth a look.
Thanks for that but already jumped over that when I got the truck
To wire the fuel pump directly you will need to install a wire from the fuse box to the pump. Use a circuit that is only energized when the ignition switch is on. I would be cleaning and checking all the connections as an intermittent problem is almost certainly a bad connection somewhere. The inertia switch is a safety device so I would not eliminate it.
