Solution

1. Preparation

Gather Tools:
- OBD-II scanner
- Fuel pressure gauge
- Multimeter
- Socket set
- Screwdrivers
- Safety glasses and gloves
Safety Warning: Disconnect the negative battery terminal before working on the fuel system to prevent electrical shock or fire.

2. Access the Fuel Pump

Remove Rear Seat or Access Panel: Depending on the configuration, either remove the rear seat or the access panel in the trunk to reach the fuel pump.
Disconnect Electrical Connections: Carefully disconnect the wiring harness from the fuel pump.

3. Test the Fuel Pump

Check for Voltage: Using a multimeter, measure the voltage at the fuel pump connector while a helper turns the ignition key to the “ON” position. It should read approximately 12 volts.
Test Fuel Pressure: Connect the fuel pressure gauge to the fuel rail, start the engine, and observe the pressure reading. It should stabilize within the specified range.

4. Replace the Fuel Pump (if necessary)

Remove Fuel Lines: Relieve fuel pressure by removing the fuel pump fuse and cranking the engine for a few seconds. Then, disconnect the fuel lines using the proper fittings.
Unbolt and Remove Pump Assembly: Remove the retaining bolts for the fuel pump assembly and lift it out of the tank. Replace the fuel pump with a new one, ensuring the rubber seals are properly seated.
Reassemble: Reinstall the fuel pump assembly, reconnect fuel lines, and plug in the electrical connections.
