Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety.
Relieve fuel system pressure by removing the fuel pump relay and starting the engine until it stalls.

2. Access Fuel Pump

Remove the rear seat or access panel to reach the fuel pump access cover.
Unscrew and remove the access cover.

3. Inspect and Test Fuel Pump

Disconnect the electrical connector from the fuel pump.
Use a multimeter to check for power and ground at the connector (should show battery voltage).
If no power, trace back to the fuel pump relay and fuse.
If power is present, proceed to remove the fuel pump assembly.

4. Replace Fuel Pump (if necessary)

Detach the fuel lines from the fuel pump assembly.
Unscrew the retaining ring and carefully lift out the fuel pump assembly.
Replace with a new fuel pump, ensuring it matches OEM specifications.
Reinstall the fuel pump assembly and reconnect fuel lines.

5. Reassemble and Test

Reattach the access cover and secure it.
Reconnect the battery and reinstall the rear seat if removed.
Start the engine and check for leaks.
