Solution

1. Preparation

Gather necessary tools: multimeter, socket set, flashlight, fuse tester.
Ensure the vehicle is in park with the parking brake engaged.
Disconnect the negative battery terminal to prevent any electrical shorts.

2. Battery Inspection

Remove the battery terminals (negative first, then positive).
Clean any corrosion from the terminals using a wire brush and a solution of baking soda and water.
Reconnect the terminals securely and ensure they are tight.

3. Ignition Switch Replacement (if faulty)

Remove the steering column covers using a socket set.
Disconnect the electrical connector from the ignition switch.
Remove the screws securing the ignition switch and carefully pull it out.
Install the new ignition switch by reversing the removal steps, ensuring all connections are secure.

4. Fuse and Relay Replacement

Locate the fuse box and identify the ignition and starter fuses.
Remove any blown fuses and replace them with new ones of the same amperage.
If the starter relay was found to be faulty, replace it with a new relay.
