Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety.
Ensure the vehicle is on a flat surface and securely lifted if needed.

2. Inspect and Replace Fuel Filter

Locate the fuel filter (usually near the fuel tank or along the fuel line).
Relieve fuel system pressure by removing the fuel pump fuse and starting the engine until it stalls.
Disconnect the fuel lines from the filter using a line wrench.
Remove the old fuel filter and install the new one, ensuring the correct orientation.
Reconnect the fuel lines and put the fuel pump fuse back.

3. Check and Replace Spark Plugs

Remove the ignition coil covers (if applicable) using a socket set.
Disconnect the ignition coil connectors and remove the coils.
Remove the spark plugs using a spark plug socket and inspect them for wear or damage.
Replace with new spark plugs, ensuring they are gapped correctly as per manufacturer specifications.
Reinstall the ignition coils and covers.

4. Test and Replace Fuel Pump (if necessary)

Use a fuel pressure gauge to test the fuel pump's pressure.
If pressure is below specifications, remove the fuel pump from the tank.
Install the new fuel pump, ensuring all seals are replaced and connections are secure.
Reconnect the fuel lines and reassemble any components removed.
