Ford Repair Questions? Ask a Mechanic for Answers ASAP
Hello, my name is***** and thanks for your question.
The most common problem I see for this concern is the fuel pump relay failing in the interior fuse box. The relay is integrated into the fuse box and cannot be replaced separately. The repair is replacing the fuse box. Of course this would need to be verified by having the concern present and verifying no voltage present out of the relay when cranking the engine. When this concern is intermittent it can be very difficult to diagnose properly.
