Solution

1. Preparation

Gather tools and safety equipment.
Tools Required:
- Multimeter
- Socket set
- Torque wrench
- Wrench set
Ensure the vehicle is parked on a flat surface and the ignition is off.

2. Battery Inspection and Replacement

Inspect the Battery:
- Remove the battery terminals (negative first, then positive).
- Clean any corrosion from the terminals and battery posts using a wire brush.
Test the Battery:
- Connect the multimeter to the battery terminals to measure voltage.
- If the voltage is below 12.4 volts, charge the battery or replace it if it cannot hold a charge.
Reinstall Battery:
- Reconnect the battery terminals (positive first, then negative) and ensure they are tight.

3. Starter Relay and Starter Motor Inspection

Check Starter Relay:
- Locate the starter relay in the fuse box.
- Swap the starter relay with another relay of the same type to test functionality.
Inspect Starter Motor:
- If the relay is functioning, locate the starter motor.
- Disconnect the wiring harness and check for loose connections.
- Test the starter motor directly with a jump wire from the battery to check for operation.

4. Replace Starter Motor (if necessary)

Remove Starter Motor:
- Disconnect the battery again (negative terminal first).
- Unbolt the starter motor from the engine block using a socket set.
- Remove the wiring harness connected to the starter.
Install New Starter Motor:
- Position the new starter motor in place.
- Reconnect the wiring harness and secure the motor with bolts, tightening them to the specified torque (typically around 10-15 lb-ft).
- Reconnect the battery terminals.
