Solution

1. Preparation

Tools Required:
- Multimeter
- Socket set
- Jumper cables
- Screwdrivers
Safety Warnings:
- Disconnect the battery before working on electrical systems.

2. Battery Inspection

Sub-steps:
1. If battery voltage is below 12.4 volts, charge the battery using a battery charger or attempt a jump start.
2. Clean any corrosion from battery terminals using a wire brush or battery cleaner.
3. Ensure connections are tight and secure.

3. Starter Motor Check

Sub-steps:
1. Locate the starter motor; it is typically found near the transmission.
2. Use a multimeter to check for voltage at the starter terminal while someone turns the ignition key to the "start" position.
3. If voltage is present but the starter does not engage, remove the starter motor for further inspection.

4. Starter Motor Replacement (if necessary)

Sub-steps:
1. Disconnect the negative battery terminal.
2. Remove any components obstructing access to the starter motor (e.g., air intake duct).
3. Unbolt the starter motor from its mount using the appropriate socket size.
4. Disconnect the wiring harness from the starter.
5. Install the new starter motor by reversing the steps, ensuring all connections are secure.
