Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the vehicle's battery to ensure safety.
Relieve fuel system pressure by removing the fuel pump fuse and starting the engine until it stalls.

2. Remove Fuel Pump

Locate the fuel pump access panel beneath the rear seat or in the trunk area.
Remove the access panel screws and carefully lift the panel.
Disconnect the electrical connector from the fuel pump.
Carefully detach the fuel lines from the fuel pump, using a line removal tool if necessary.
Unbolt the fuel pump assembly from the tank using a socket set.

3. Inspect and Replace

Remove the old fuel pump from the assembly, and inspect the fuel filter and sock for clogs.
Install the new fuel pump into the assembly, ensuring it is seated properly.
Reconnect the fuel lines and electrical connector securely.
Reinstall the fuel pump assembly back into the fuel tank, tightening bolts to the specified torque value (refer to service manual for exact torque specifications).

4. Reassemble and Test

Replace the access panel and its screws.
Reconnect the vehicle's battery.
Reinstall the fuel pump fuse and turn the ignition key to the 'ON' position to prime the fuel system.
Start the engine and check for leaks or abnormal noises.
