Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the negative battery terminal for safety.

2. Battery Inspection and Replacement

Inspect Battery:
- Clean any corrosion from battery terminals using a wire brush.
- Check the battery's condition; if it is more than 4-5 years old, consider replacement.
Replace Battery (if necessary):
- Disconnect the positive terminal first, followed by the negative terminal.
- Remove the old battery and install the new one, connecting the positive terminal first, then the negative terminal.
- Ensure the battery is securely mounted.

3. Fuel System Check and Repair

Fuel Pump Operation:
- Turn the ignition to the ON position (do not start) and listen for the fuel pump's humming sound.
- If silent, check the fuse and relay for the fuel pump.
Fuel Pressure Test:
- Connect a fuel pressure gauge to the fuel rail.
- Turn the ignition to the ON position and check the pressure; it should be within manufacturer specifications (usually around 30-50 psi).
- If pressure is low, replace the fuel pump and filter if necessary.

4. Ignition System Inspection and Repair

Check Spark Plugs:
- Remove spark plugs using a socket wrench.
- Inspect for wear, carbon buildup, or damage; replace if necessary (use OEM recommended spark plugs).
Inspect Ignition Coils:
- Test each ignition coil with a multimeter to ensure proper resistance.
- Replace any faulty ignition coils.
