Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety during repair.
Tools required: multimeter, OBD-II scanner, fuel pressure gauge, socket set.

2. Battery Inspection and Replacement

Inspect Battery Voltage:
- Use a multimeter to check voltage; it should read between 12.4V to 12.7V for a healthy battery.
Clean Battery Connections:
- Remove terminals and clean with a wire brush. Reconnect securely.
Replace Battery (if necessary):
- If the battery is below 12.4V, replace it with a new one that meets OEM specifications.
- Torque battery terminals to the recommended specifications.

3. Fuel System Check

Inspect Fuel Pump:
- Turn the ignition key to the "ON" position without starting the engine. Listen for the fuel pump's prime sound.
Check Fuel Pressure:
- Connect a fuel pressure gauge to the fuel rail.
- Start the engine and check that pressure meets manufacturer specifications (usually around 30-50 psi).
- If pressure is low, consider replacing the fuel pump.

4. Ignition System Inspection

Check Spark Plugs:
- Remove spark plugs and inspect for wear or carbon buildup.
- Replace any faulty spark plugs with OEM replacements.
Inspect Ignition Coils:
- Test ignition coils with a multimeter for proper resistance.
- Replace any faulty ignition coils.

5. Key Fob Battery Replacement (if applicable)

Replace Key Fob Battery:
- Open the key fob and replace the battery with a new one as per the manufacturer's specifications.
