Solution

1. Preparation

Gather tools: OBD-II scanner, fuel pressure gauge, multimeter, socket set.
Ensure safety: Disconnect the battery before starting work on electrical components.

2. Access Fuel Pump

Remove the rear seat to access the fuel pump access panel.
Unscrew the access panel using a socket set to expose the fuel pump assembly.

3. Inspect and Test Fuel Pump

Disconnect the electrical connector from the fuel pump.
Use a multimeter to test for voltage at the connector (should be around 12V when the ignition is on).
If voltage is present, remove the fuel pump from the tank and visually inspect for damage or wear.
If the pump appears faulty, replace it with a new unit.

4. Replace Fuel Filter (if necessary)

If the fuel filter is clogged, locate it along the fuel line and remove it using a socket wrench.
Install a new fuel filter, ensuring the direction of flow is correct.

5. Reassemble and Reconnect

Reinstall the fuel pump assembly into the tank and secure it properly.
Reattach the access panel and rear seat.
Reconnect the battery.
