Solution

1. Preparation

Gather tools: multimeter, socket set, screwdriver, and safety gloves.
Disconnect the negative terminal of the battery.

2. Inspect Battery Connections

Remove the battery terminals (positive first, then negative).
Clean any corrosion using a wire brush and a mixture of baking soda and water.
Reconnect the battery terminals securely.

3. Test and Replace Starter Relay

Locate the starter relay in the fuse box.
Remove the relay and inspect for any signs of damage.
If damaged, replace it with a new relay. Ensure it matches the original specifications.

4. Inspect and Test the Ignition Switch

Access the ignition switch by removing the steering column cover.
Use a multimeter to check for continuity in the switch when turned to the “Start” position.
Replace the ignition switch if it does not pass the continuity test.

5. Test or Replace Starter Motor

If the starter relay and ignition switch are functioning, check the starter motor.
Disconnect the wiring harness from the starter.
Use a jumper wire to apply voltage directly to the starter terminal; if it engages, replace the starter motor.

Tools Required:
