Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent electrical shocks.

2. Fuel System Inspection

Tools Required: Fuel pressure gauge, wrench set.
- Remove the fuel pump relay to relieve fuel pressure.
- Connect a fuel pressure gauge to the fuel rail.
- Turn the ignition key to the "ON" position without starting the engine and check the fuel pressure.
- If the pressure is below specifications (refer to service manual), replace the fuel pump or clean the fuel filter.

3. Ignition System Check

Tools Required: Spark plug socket, multimeter.
- Remove the spark plugs and inspect for wear or fouling.
- Use a multimeter to check the resistance of the ignition coils; replace any faulty coils.
- Reinstall spark plugs with a torque of 13-15 lb-ft.

4. Air Intake System Examination

Tools Required: Screwdriver set, throttle body cleaner.
- Inspect the air intake duct for cracks or disconnections.
- Remove the throttle body and clean it using throttle body cleaner.
- Reinstall the throttle body and ensure all connections are secure.

5. Battery and Charging System Test

Tools Required: Multimeter.
- Use a multimeter to check the battery voltage; it should be around 12.6 volts when off and 13.7-14.7 volts when running.
- If voltage is low, consider replacing the battery or checking the alternator.
