Solution

1. Preparation

Ensure the vehicle is in "Park" or "Neutral" and the parking brake is engaged.
Disconnect the negative battery terminal to prevent electrical shock.

2. Battery Inspection

Check Battery Voltage: Use a multimeter to test for at least 12.4 volts. If below, charge or replace the battery.
Clean Terminals: Remove battery terminals and clean them with a wire brush. Reconnect securely.

3. Fuse and Relay Check

Inspect Fuses: Locate the fuse box and check the starter fuse. Replace if blown.
Test Starter Relay: Remove the starter relay from the fuse box. Use a multimeter to check for continuity. Replace if faulty.

4. Starter Inspection

Access Starter: If the battery and relay are functioning, access the starter motor.
Test Starter: Use a multimeter to check for voltage at the starter terminal when the ignition is turned on. If no voltage, the starter may need replacement.
Check Connections: Ensure all wiring to the starter is secure and free of damage.

5. Ignition Switch Check
