Solution

1. Preparation

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

2. Inspect and Replace Fuel Filter

Locate the fuel filter (consult the service manual for specific location).
Use a wrench to disconnect the fuel lines from the filter.
Remove the old fuel filter and replace it with a new one, ensuring correct orientation.
Reconnect the fuel lines and ensure they are secure.

3. Check and Replace Fuel Pump (if necessary)

Remove the fuel tank (if the pump is in-tank) or access the pump assembly.
Disconnect the electrical connector and fuel lines from the pump.
Remove the mounting screws and lift out the old pump.
Install the new fuel pump, reversing the removal steps.
Reconnect the fuel lines and electrical connectors.

4. Test and Reassemble

Reconnect the battery and turn the ignition to the "ON" position to prime the fuel system.
Check for leaks around the fuel lines and connections.
Reassemble any components removed for access.
