Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface, and the engine is cool.
Disconnect the battery to ensure safety while working on electrical components.

2. Fuel System Inspection

Check Fuel Pump:
- Reconnect the battery.
- Turn the ignition to the "ON" position (without starting) to activate the fuel pump.
- Listen for the fuel pump sound. If no sound is heard, consider replacing the fuel pump.
Fuel Filter Replacement:
- Locate the fuel filter (typically along the fuel line).
- Using a wrench, carefully disconnect the fuel lines from the filter, ensuring to catch any fuel in a container.
- Replace the old filter with a new one, ensuring proper orientation.
- Reconnect the fuel lines securely.

3. Ignition System Check

Inspect Spark Plugs:
- Remove the ignition coil or spark plug wires.
- Take out the spark plugs using a spark plug socket.
- Inspect for wear or damage; replace if necessary with OEM or equivalent parts.
- Reinstall the spark plugs and reconnect ignition components.
Testing Ignition Coils:
- Use a multimeter to test resistance according to manufacturer specifications.
- Replace any faulty ignition coils.

4. Throttle Body Cleaning

Remove Throttle Body:
- Disconnect the intake air duct from the throttle body.
- Remove mounting bolts and carefully detach the throttle body from the intake manifold.
Clean Throttle Body:
- Spray throttle body cleaner into the throttle body and use a clean cloth or brush to remove carbon buildup.
- Ensure the throttle plate moves freely.
- Reinstall the throttle body and intake air duct, securing all components.
