Repair Instructions

Step 1: Replace Fuel Pump

If you determine the fuel pump is failing, follow these steps for replacement:

  1. Prepare the Vehicle:

    • Park the vehicle on a flat surface, turn off the ignition, and disconnect the battery.

  2. Relieve Fuel System Pressure:

    • Remove the fuel pump relay from the fuse box.
    • Start the engine and let it run until it stalls to relieve fuel pressure.

  3. Access the Fuel Pump:

    • If the Explorer has a rear access panel, remove it to reach the fuel pump.
    • If not, you may need to drop the fuel tank. Support the tank with a jack and remove the bolts securing it.

  4. Disconnect Fuel Lines and Electrical Connectors:

    • Carefully disconnect the fuel lines using a fuel line disconnect tool.
    • Disconnect the electrical connector from the fuel pump.

  5. Remove the Old Fuel Pump:

    • Unscrew the retaining ring or bolts holding the fuel pump in place.
    • Remove the old pump and fuel sender assembly.

  6. Install the New Fuel Pump:

    • Install the new pump in reverse order of removal.
    • Make sure to replace any seals or O-rings to prevent leaks.

  7. Reassemble Everything:

    • Reconnect the fuel lines and electrical connectors.
    • If you dropped the tank, raise it back into place and secure it with bolts.

  8. Reconnect the Battery:

    • Reconnect the battery and reinstall the fuel pump relay.

  9. Test the System:

    • Turn the ignition key to the "ON" position and check for leaks.
    • Start the engine and verify proper operation.

Step 2: Check Related Components

If the fuel pump replacement does not resolve the issue, check the following components:

  1. Fuel Pump Relay and Fuse:

    • Test and replace if necessary.

  2. Fuel Filter:

    • Replace if clogged, as this can affect fuel flow.

  3. Fuel Pressure Regulator:

    • Inspect and replace if malfunctioning.

  4. Wiring and Connectors:

    • Inspect for any damaged wiring or corroded connectors leading to the fuel pump.

By following these detailed steps, you can diagnose and address a failing fuel pump in the Ford Explorer Sixth Generation effectively.
