I was driving my sport trac when it suddenly died on me. We are leaning toward the fuel pump. But is there any other causes for fuel to not get to the engine? We changed the fuel filter out already

 

Welcome to the forum

There is an impact switch under the carpet/under dash, passenger side that sometimes trips if someone stamps their feet on that foot well, good to check.

Under the hood in the power distribution box, one of the relays is for the fuel pump, switch the relays. There should be 3, rotate them all clockwise, like musical chairs..

Last fuel filler cap off, ear to filler, key on do you hear the pump??

Last resort, fuel pressure gauge on the fuel rail........

NOTE: What makes you think it is fuel related???? Philip

 

It was actually the crank sensor and the harmonic balance. The switch and pump were my first guesses. Apparently this is a common problem with my truck. The belt slipped to the outside of the pulley, so from above it looked like the belt was fine.

Thank you for you input

 

I have a 03 explorer sport trac ive changed the fuel pump switched relays and checked the inertia switch but the fuel pump still wont run any suggestions

 

Have you checked for voltage to the inertia switch when the key is first turned to the Run position? Remember, this will only have power for a second or so to prime the system, so a test light will be your friend for this check.
