Solution

1. Preparation

Gather all necessary tools and parts, ensuring you have safety equipment.
Disconnect the negative terminal of the battery to prevent accidental short circuits.

2. Battery Inspection

Inspect Battery Terminals:
- Clean any corrosion from battery terminals using a wire brush.
- Tighten loose connections.
Test Battery:
- If the battery voltage is below 12.6 volts, recharge or replace the battery as needed.

3. Starter Relay and Fuse Check

Remove Starter Relay:
- Identify and remove the starter relay from the fuse box.
Swap Relay:
- Replace with another relay of the same type to test functionality.
Check Fuses:
- Inspect all related fuses; replace any that are blown.

4. Starter Inspection

Access the Starter:
- Safely elevate the vehicle and secure it on jack stands.
Inspect Starter Connections:
- Check for tight connections at the starter solenoid and motor.
Test Starter:
- If all connections are secure and issue persists, replace the starter motor.

5. Reassemble and Test

Reconnect the battery terminals, starting with the positive terminal followed by the negative terminal.
Perform a final inspection to ensure all components are reassembled correctly.
