Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working.

2. Fuel System Inspection

Tools Required: Fuel pressure gauge, safety glasses, gloves.
Instructions:
1. Connect the fuel pressure gauge to the fuel rail service port.
2. Turn the ignition to the "ON" position without starting the engine to check the fuel pressure reading.
3. If the pressure is below specifications, check the fuel pump relay and fuse.
4. If necessary, replace the fuel pump.

3. Spark Plug and Ignition Coil Replacement

Tools Required: Socket set, torque wrench.
Instructions:
1. Remove the ignition coil cover (if equipped) by unscrewing bolts.
2. Disconnect the electrical connector from each ignition coil.
3. Remove the ignition coils using the socket set.
4. Check the condition of the spark plugs; replace them if fouled or worn.
5. Install new spark plugs and torque them to manufacturer specifications (typically 13 lb-ft).
6. Reinstall the ignition coils and reconnect electrical connectors.

4. Battery and Electrical System Check

Tools Required: Multimeter.
Instructions:
1. Use the multimeter to check the battery voltage; it should read between 12.4V and 12.7V for a fully charged battery.
2. Clean battery terminals and ensure connections are tight.
3. If the battery is weak, consider replacing it.
