Asked by for the 1990 Ford F-350
there are many reasons for no power to the pump. the fuse could be blown from a bad pump. the inertia switch could be tripped from towing or a hard hit. the relay, which is on the left front fender skirt with the power relay. and last, it could be wiring.

you need someone who can track this down and give you a bid for repairs.

fuel delivery issues are common on these trucks.

thanks for using repairpal
