Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the negative terminal of the battery for safety.
Ensure the vehicle is on a level surface and secure with wheel chocks.

2. Battery Inspection

Check the battery voltage with a multimeter; it should be over 12.4 volts.
Clean battery terminals with a wire brush if corrosion is detected.
Tighten any loose connections.

3. Fuel System Check

Fuel Pump Functionality:
- Turn the ignition key to the "ON" position without starting the engine.
- Listen for the fuel pump priming sound for a few seconds.
Fuel Pressure Testing:
- Attach a fuel pressure gauge to the fuel rail service port.
- Turn the ignition to "ON" and check that the pressure meets manufacturer specifications (typically 50-60 psi).
- If pressure is low, replace the fuel pump.

4. Ignition System Service

Remove and inspect spark plugs for wear or fouling.
Replace any damaged or worn spark plugs with OEM parts.
Test ignition coils with a multimeter to ensure they are within resistance specifications.
Replace faulty ignition coils if needed.

5. Sensor Inspection

Locate the crankshaft and camshaft position sensors.
Check the wiring and connectors for damage or corrosion.
Use a multimeter to test the sensors for proper resistance.
Replace any faulty sensors.
