Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, fuel pressure gauge, safety glasses, gloves.
Disconnect the negative battery terminal to prevent electrical shorts while working.

2. Check Fuel Pump Operation

Reconnect the battery.
Turn the ignition key to the "ON" position (do not start the engine) and listen for the fuel pump prime sound.
If you do not hear the pump, use a multimeter to check the voltage at the fuel pump connector while the ignition is on.
- Tools Required: Multimeter
- Safety Warning: Ensure the area is well-ventilated to avoid fuel vapors.

3. Inspect Fuel System Components

If the fuel pump is not functioning, replace the fuel pump assembly.
- Remove the rear seat cushion to access the fuel pump access panel.
- Disconnect the fuel lines and electrical connectors from the pump.
- Unbolt and remove the pump assembly from the tank.
- Install the new pump by reversing the removal steps and ensure all connections are secure.

4. Test Fuel Pressure

Connect a fuel pressure gauge to the fuel rail service port.
Turn the ignition to the "ON" position and check the fuel pressure reading.
- Specifications: Refer to the service manual for the correct fuel pressure range.
If pressure is low, check for clogs in the fuel filter or replace it if necessary.

5. Final Assembly and Recheck

Reinstall any components removed during the process.
Ensure the fuel filler cap is tight and properly sealed.
Reconnect the negative battery terminal.
