Where is the reset button for fuel pump on 2001 ford explorer sport?

There is no reset button for the fuel pump on a 2001 Ford Explorer Sport (or any car, for that matter). Fuel pumps are usually activated electrically by the car's computer system. If you're having fuel pump issues, the problem is likely a faulty pump, a problem with the electrical system (fuses, wiring, the pump relay), or possibly a fuel pump control module. You'll need to diagnose the specific problem before attempting any repairs. A qualified mechanic can help with this.
