Reattach the air filter housing cover and secure it.

3. Fuel System Check

Connect a fuel pressure gauge to the fuel rail.
Turn the ignition to the "ON" position without starting the engine and check the pressure reading.
If pressure is low, inspect the fuel pump and fuel filter for blockage or failure.
Replace the fuel filter if necessary and ensure the fuel lines are free of leaks.

4. Ignition System Inspection

Remove the ignition coils using a ratchet and socket.
Inspect the spark plugs for wear or damage; replace if necessary.
Reinstall the ignition coils securely, ensuring proper connection.
