Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is in park with the parking brake engaged.
Disconnect the negative battery terminal to prevent electric shock.

2. Clean and Secure Battery Connections

Remove the battery terminals (negative first, then positive).
Clean any corrosion from the terminals and battery posts using a wire brush.
Reconnect the battery terminals securely (positive first, then negative).

3. Test and Replace the Battery (if needed)

Reconnect the battery and check the voltage again with a multimeter.
- If below 12.4 volts, replace the battery with a compatible one (typically a Group 65 battery).
Ensure the new battery is properly charged before installation.

4. Inspect and Replace the Starter Motor (if needed)

If the starter motor is found to be faulty during testing, remove it from the engine.
1. Disconnect any wiring harnesses from the starter.
2. Remove the mounting bolts using a socket set.
3. Carefully pull the starter motor out from its location.
Install the new starter motor by reversing the removal steps and ensuring all connections are tight.

5. Verify Ignition Switch Operation

If the starter motor is not the issue, further inspect the ignition switch.
Remove the steering column cover to access the ignition switch.
Test the ignition switch continuity with a multimeter; replace if defective.
