Solution

1. Preparation

Gather tools: multimeter, socket set, screwdriver, and safety gloves.
Ensure the vehicle is in park (or neutral) and the parking brake is engaged.

2. Inspect and Clean Battery Connections

Disconnect the negative battery terminal first, followed by the positive terminal.
Clean the terminals and cable ends with a wire brush to remove corrosion.
Reconnect the positive terminal first, then the negative terminal, ensuring they are tight.

3. Test and Replace the Starter Relay

Locate the starter relay in the fuse box based on the owner's manual.
Remove the relay and test it using a multimeter for continuity.
If faulty, replace it with a new relay of the same specifications.

4. Check and Replace the Starter

If the starter relay is functioning, proceed to inspect the starter.
Disconnect the battery again.
Remove the starter by unbolting it from the engine block and disconnecting the electrical connectors.
Inspect the starter for signs of wear or damage; if defective, replace it with a new starter.
Reinstall the starter, ensuring all connections are secure.

5. Verify Ignition Switch

If the starter is not the issue, check the ignition switch.
Remove the steering column covers to access the ignition switch.
Test for continuity with a multimeter when the key is turned to the start position.
Replace the ignition switch if it does not show continuity.
