Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the battery to ensure safety while working on the vehicle.
Allow the engine to cool down if it has been running.

2. Inspect and Replace Fuel Filter

Locate the fuel filter; it is usually along the fuel line.
Use a socket set to remove the fuel filter, taking care to catch any fuel that may spill.
Install the new fuel filter in the correct orientation, ensuring all connections are secure.

3. Check and Replace Spark Plugs

Remove the ignition coil covers if applicable (use the socket set).
Disconnect the ignition coils and remove them from the spark plugs.
Use a spark plug socket to remove the old spark plugs.
Inspect the old plugs for wear; replace them with new ones, ensuring they are gapped correctly.
Reinstall the ignition coils and covers, ensuring all connections are secure.

4. Test and Replace Fuel Pump (if necessary)

If the fuel pump is not operating, access it by removing the rear seat or accessing the undercarriage.
Disconnect the electrical connector and fuel lines from the fuel pump.
Remove the fuel pump assembly and replace it with a new unit.
Reconnect all lines and connectors, ensuring they are secure.
