Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Replace Fuel Filter

Locate the fuel filter (usually along the fuel line under the vehicle).
Use a socket set to remove the fuel filter.
Replace with a new fuel filter, ensuring the flow direction is correct.
Reconnect any hoses and clamps securely.

3. Test and Replace Fuel Pump (if necessary)

Remove the fuel pump access cover (if applicable) or lift the vehicle to access the pump.
Disconnect the electrical connector and fuel lines from the pump.
Remove the mounting bolts and lift out the old fuel pump.
Install the new fuel pump, ensuring all connections are secure.
Reassemble any components removed during access.

4. Inspect and Replace Spark Plugs

Remove the ignition coil(s) to access the spark plugs.
Use a spark plug socket to remove each spark plug.
Inspect for wear, fouling, or damage; replace with new plugs if necessary.
Reinstall the ignition coils, ensuring they are seated properly.

5. Inspect Vacuum Lines

Visually inspect all vacuum lines connected to the intake manifold and throttle body.
Replace any cracked, damaged, or disconnected hoses.
Use a smoke test to detect hard-to-find leaks if needed.
