Solution

1. Preparation

Gather tools and parts.
Disconnect the negative battery terminal to ensure safety during repairs.

2. Fuel System Inspection

Check Fuel Pump Operation
- Turn the ignition key to the "ON" position without starting the engine.
- Listen for the fuel pump's operational noise.
- If no sound is heard, test the fuel pump relay and wiring.
Replace Fuel Filter
- Locate the fuel filter along the fuel line.
- Use a line wrench to disconnect the fuel lines from the filter.
- Remove the old filter and install the new one, ensuring proper orientation.
- Reconnect the fuel lines and check for leaks.

3. Ignition System Inspection

Inspect and Replace Spark Plugs
- Remove the ignition coil cover (if applicable).
- Unscrew the spark plugs using a spark plug socket and ratchet.
- Inspect the spark plugs for wear; replace if necessary.
- Reinstall new spark plugs and torque to manufacturer specifications (usually around 13-15 lb-ft).
Check Ignition Coils
- Inspect each ignition coil for cracks or damage.
- Use a multimeter to test the coil's resistance; replace any faulty coils.

4. Intake System Inspection

Throttle Body Cleaning
- Remove the air intake duct connected to the throttle body.
- Use throttle body cleaner and a soft cloth to clean the throttle body.
- Ensure the throttle plate operates freely.
- Reconnect the duct and secure all clamps.

5. Final Checks

Reconnect the negative battery terminal.
Start the engine and allow it to idle, checking for any unusual noises or behaviors.
