Solution

1. Preparation

Gather tools and parts needed.
Disconnect the negative battery cable to ensure safety.
Relieve fuel system pressure by removing the fuel pump relay and starting the engine until it stalls.

2. Fuel Pump Replacement

Remove the Fuel Tank
- Support the fuel tank with a jack.
- Remove the securing bolts and lower the tank carefully.
- Disconnect the fuel lines and electrical connectors.
Replace the Fuel Pump
- Remove the retaining ring holding the fuel pump in place.
- Take out the old fuel pump and replace it with a new one.
- Ensure the fuel pump strainer is installed properly.
Reinstall the Fuel Tank
- Reconnect the fuel lines and electrical connectors.
- Position the fuel tank back in place and secure it with bolts.

3. Fuel Filter Replacement

Locate the Fuel Filter
- Depending on the model, the fuel filter may be integrated with the fuel pump or located along the fuel line.
Replace the Fuel Filter
- If separate, disconnect the fuel lines from the old filter.
- Remove the old filter and install the new one, ensuring correct flow direction.

4. Fuel Injector Service

Remove Fuel Injectors
- Disconnect the electrical connectors from each injector.
- Remove the fuel rail bolts and lift the rail with injectors away from the engine.
