Solution

1. Preparation

Gather tools: Multimeter, socket set, screwdrivers.
Ensure the vehicle is in park (automatic) or neutral (manual) with the parking brake engaged.

2. Battery Inspection

Disconnect the negative battery terminal using a socket set.
Clean any corrosion from the battery terminals with a wire brush.
Reconnect the battery terminals securely.

3. Starter Relay Check

Locate the fuse box under the dashboard or engine bay.
Identify the starter relay and carefully remove it.
Inspect the relay for any visible damage.
If the relay appears functional, swap it with a similar relay to test functionality.

4. Starter Solenoid Testing

Locate the starter motor under the vehicle.
Inspect the wiring harness connected to the starter solenoid for damage.
Use a multimeter to check for voltage at the solenoid terminal while someone turns the ignition key to the start position.
- If voltage is present, the starter may be faulty.
- If no voltage, further investigate wiring and ignition switch.

5. Starter Replacement (if necessary)

Disconnect the negative battery terminal again.
Remove the starter motor by disconnecting the electrical connections and the mounting bolts.
Install the new starter by reversing the disassembly steps.
Torque the mounting bolts to the manufacturer’s specifications (typically around 20-25 ft-lbs).
