Solution

1. Preparation

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

2. Battery Inspection and Replacement

Inspect the battery terminals for tightness and corrosion.
- Use a wire brush to clean any corrosion.
If the battery voltage is low, charge the battery or replace it if defective.
- Tools: Battery charger or new battery, socket set.
Reconnect the battery terminals securely.

3. Starter Motor Inspection

Locate the starter motor under the vehicle.
Disconnect the electrical connector from the starter motor.
Use a multimeter to check for voltage at the starter terminal when the key is turned to the start position.
- If no voltage is present, check the ignition switch and starter relay.
If voltage is present but the starter does not engage, remove the starter motor.
- Tools: Socket set, wrench, jack stands.
Test the starter motor by bench testing it.
- If faulty, replace with a new starter motor.

4. Fuel System Check

Check the fuel pump relay and fuses.
- Replace any blown fuses.
If the fuel pump is not operating, replace the fuel pump.
- Tools: Fuel pressure gauge, socket set, safety goggles.
Reconnect all components and ensure proper operation.
