Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety during repairs.

2. Inspect and Test the Fuel System

Fuel Pump:
- Locate the fuel pump access panel (if applicable) or remove the rear seat to access the pump.
- Use a fuel pressure gauge to measure the fuel pressure at the fuel rail.
  - Normal pressure: Consult the service manual for specifications.
- If pressure is low, replace the fuel pump.
Fuel Filter:
- Locate the fuel filter and inspect for clogs or restrictions.
- Replace if necessary, ensuring to use OEM parts for compatibility.

3. Check Ignition System

Spark Plugs and Coils:
- Remove the spark plug wires and inspect the condition of the spark plugs for wear or fouling.
- Replace spark plugs if they appear worn or damaged.
- Test ignition coils with a multimeter to check for proper resistance; replace if defective.

4. Inspect Battery and Charging System

Battery:
- Check battery voltage with a multimeter (should be around 12.6V when fully charged).
- Clean battery terminals and ensure tight connections.
Alternator:
- Start the engine and measure voltage across the battery terminals; it should be between 13.7V to 14.7V.
- If voltage is low, consider replacing the alternator.

5. Vacuum Leak Inspection

Inspect all hoses connected to the intake manifold for cracks or disconnections.
Use a smoke machine or spray carb cleaner around the intake area to detect leaks.
Replace any damaged hoses or gaskets.
