Solution

1. Preparation

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

2. Inspect and Replace Fuel Filter

Locate the fuel filter in the fuel line.
Use appropriate wrenches to disconnect the fuel lines from the filter.
Remove the old fuel filter and replace it with a new one, ensuring the flow direction matches the vehicle's specifications.
Reconnect the fuel lines and check for leaks.

3. Test and Replace Fuel Pump (if necessary)

Use a multimeter to check the fuel pump relay and wiring for continuity.
If the pump is defective, drain the fuel tank and remove it.
Disconnect the fuel pump wiring and remove the pump from the sending unit.
Install the new fuel pump and reassemble the fuel tank.
Reconnect the wiring and relays, ensuring all connections are secure.

4. Inspect and Replace Spark Plugs

Remove the ignition coil covers and coils to access the spark plugs.
Use a spark plug socket to remove the old spark plugs, inspecting them for wear or deposits.
Install new spark plugs, ensuring they are gapped correctly to manufacturer specifications.
Reinstall the ignition coils and covers securely.

5. Check and Repair Vacuum Leaks

Inspect all vacuum hoses connected to the intake manifold for cracks or disconnections.
Replace any damaged hoses.
Use a smoke machine or carburetor cleaner to identify and seal any leaks around gaskets.
