Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the ignition is turned off.
Disconnect the negative battery terminal to ensure safety.

2. Inspect and Replace Fuel Pump Fuse

Locate the fuse box; refer to the owner’s manual for exact location.
Remove the fuel pump fuse using a fuse puller.
Inspect the fuse for continuity; replace if blown.
Reinstall the new fuse securely.

3. Test and Replace Fuel Pump (if necessary)

Locate the fuel pump access panel (usually under the rear seat or trunk).
Remove the access panel and disconnect the electrical connector from the fuel pump.
Use a multimeter to test the pump for voltage supply when the ignition is turned on; if no voltage, investigate wiring.
If the pump is faulty, remove it from the fuel tank:
- Safely relieve fuel system pressure.
- Disconnect fuel lines and electrical connectors.
- Unscrew retaining ring and lift the pump assembly out.
Install the new fuel pump by reversing the removal steps, ensuring proper alignment and sealing.

4. Check Fuel Lines

Inspect all visible fuel lines for cracks or leaks.
Replace any damaged lines with OEM parts to ensure proper fit and durability.

5. Reconnect Battery and Test

Reconnect the negative battery terminal.
Turn the ignition key to the "ON" position to prime the fuel system.
Attempt to start the engine.
