  Q: How to remove and install the fuel pump and sending unit assembly on Ford Explorer Sport Trac?

  A: To perform this procedure, you will need to have a fuel pump and sending unit assembly. The tool can be purchased in almost any auto parts store or it can be installed about ten inches behind the fuel filter on some models. In case the tank is not empty, it is advisable to siphon off any residual fuel before proceeding. Thus, first, relieve the fuel pressure and disconnect the battery then raise the vehicle securely using jack stands. Next, remove the Fuel Tank, disconnect the fuel feed and return lines from the fuel pump module then unscrew the lock ring or release mounting bolts or plastic retaining ring according to your model type. Lift out of the tank the fuel pump/sending unit assembly, inspect if necessary an O-ring at the top of opening in the tank, and replace it. Remove bolt securing band clamp for mounting of fuel pump and lower hose clamp for electrical connector as well as strainer which requires cleaning or replacement. Wipe clean surfaces, lubricate new seal ring, install O-ring onto the groove on suction adapter's bottom surface, and guide assembly into the tank.

  Q: How to check the Fuel Pump and fuel pressure on Ford Explorer Sport Trac?

  A: A gauge and adapter set will be needed to perform a fuel pressure test. Keep in mind that the fuel pump functions when the engine is cranking or running and receives ignition reference pulses from the electronic ignition system. Once you have released the fuel pressure, it is advisable to cover up the fuel connections with a towel. If your car has an electric pump, you can hear it immediately when someone turns on ignition key; there should be a whirring noise heard at the gas filler opening. If not, check out fuel pump fuse, inspecting the fuel relay and wiring as well as ensure inertia switch works properly. At the relay connector, you can verify voltage, and at the fuel pump harness connector just check for battery voltage. In case voltage is present but still there is no action from the pump, check for continuity to ground at the fuel pump harness connector and replace if necessary. To check operating pressure, relieve fuel system pressure, attach a gauge to the test port, and start the engine. Troubleshoot any problems based on this gauge reading.
