Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical hazards.
Relieve fuel system pressure by removing the fuel pump relay and starting the engine until it stalls.

2. Access the Fuel Pump

Tools Required: Socket set, screwdriver set, safety glasses, and gloves.
Raise the vehicle using jack stands to access the fuel tank if necessary, or remove the rear seat if the fuel pump access panel is located there.
Remove any covering or panel that conceals the fuel pump.

3. Inspect the Fuel Pump

Disconnect the electrical connector from the fuel pump carefully.
Use a multimeter to test the power supply to the fuel pump connector; ensure it receives voltage when the ignition is on.
Check for any foreign particles or debris in the fuel tank that could be obstructing the pump.

4. Replace the Fuel Pump (if necessary)

Parts Required: New fuel pump assembly (ensure compatibility with the 2020-present Ford Explorer).
Remove the fuel lines from the pump assembly, taking care to have a rag handy to catch any fuel spills.
Unscrew the retaining ring or bolts holding the pump in place and carefully remove the old pump.
Install the new fuel pump, securing it with the retaining ring or bolts and reconnecting the fuel lines.
Reconnect the electrical connector to the new fuel pump.

5. Reassemble and Test

Reinstall any covering or panel removed for access.
Reconnect the negative battery terminal.
Turn the ignition to the "ON" position to prime the fuel system and check for leaks.
Start the engine and observe its operation, ensuring proper functionality.
