Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the negative battery terminal to prevent electric shock.
Allow the vehicle to cool down if it has been running.

2. Replace Fuel Pump Relay

Locate the fuel pump relay in the fuse box (refer to the owner's manual for exact location).
Remove the faulty relay by pulling it out of the socket.
Insert the new relay into the socket firmly.

3. Replace Fuel Pump Fuse

Locate the fuel pump fuse in the fuse box.
Use a fuse puller or pliers to remove the blown fuse.
Insert a new fuse of the same amperage rating into the fuse socket.

4. Fuel Pressure Test and Replacement

Attach the fuel pressure gauge to the fuel rail test port.
Turn the ignition to the "ON" position and record the pressure reading.
If pressure is below specifications, proceed to replace the fuel pump:
1. Drain the fuel tank.
2. Disconnect the fuel lines and electrical connectors from the fuel pump assembly.
3. Remove the fuel pump assembly from the tank.
4. Replace the old fuel pump with a new one, ensuring proper alignment and sealing.
5. Reassemble and reconnect all components, ensuring there are no leaks.

5. Reconnect Battery

Reconnect the negative battery terminal and ensure it is secure.
