Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the negative battery terminal to ensure electrical safety.
Relieve fuel system pressure by removing the fuel pump relay and starting the engine until it stalls.

2. Inspecting the Fuel Pump

Tools Required: Fuel pressure gauge, multimeter.
Remove the fuel pump access cover from the vehicle’s undercarriage.
Disconnect the electrical connector from the fuel pump.
Test the fuel pump with a multimeter to ensure it's receiving power when the ignition is on.
If the pump isn't receiving power, trace the wiring and inspect the fuel pump relay.

3. Replacing the Fuel Filter

Parts Required: New fuel filter.
Locate the fuel filter; it may be under the vehicle or within the engine bay.
Use line wrenches to disconnect fuel lines from the filter, taking care to capture any spilled fuel.
Remove the old filter and replace it with the new one, ensuring the flow direction is correct.
Reconnect the fuel lines securely.

4. Replacing the Fuel Pump (if necessary)

Parts Required: New fuel pump.
If the pump is defective, remove it from the fuel tank following manufacturer instructions, which may involve lowering the tank.
Install the new fuel pump, ensuring all seals and gaskets are in place.
Reinstall the fuel tank and secure it properly.

5. Testing the Fuel Injectors

Tools Required: Multimeter, injector tester (if available).
Remove the electrical connectors from the fuel injectors.
Use a multimeter to check the resistance of each injector; it should be within specifications as mentioned in the service manual.
If injectors are faulty, replace them with new units.
