Solution

1. Preparation

Gather tools: multimeter, wrench set, jumper wire, and screwdriver.
Ensure the vehicle is in park (automatic) or neutral (manual) and the parking brake is engaged.

2. Battery Inspection

Disconnect the negative battery terminal to prevent accidental short circuits.
Clean any corrosion from the battery terminals using a wire brush.
Reconnect the terminals securely and ensure a tight fit.

3. Starter Motor Testing

Locate the starter motor, usually found near the transmission.
Disconnect the wiring harness from the starter.
Use a jumper wire to connect the positive terminal of the battery directly to the starter terminal. If the starter engages and the engine turns over, the starter is functional.

4. Check Starter Relay and Fuses

Locate the fuse box (usually under the dashboard or in the engine compartment).
Check the starter relay and replace it if faulty.
Inspect the fuses related to the starting system; replace any blown fuses.

5. Ignition Switch Examination

If the starter motor and relay are functioning, check the ignition switch.
Remove the steering column cover if necessary to access the ignition switch.
Test the ignition switch with a multimeter; replace if it does not provide continuity.
