Solution

1. Battery Inspection

Sub-steps:
- Turn off all electrical accessories and remove the key from the ignition.
- Disconnect the negative battery terminal first, followed by the positive terminal.
- Clean any corrosion from the battery terminals using a wire brush and a mixture of baking soda and water.
- Reconnect the positive terminal first, followed by the negative terminal.
Tools Required: Wire brush, baking soda, water.

2. Battery Replacement (if necessary)

Sub-steps:
- If the battery voltage is below 12.4 volts, remove the battery by loosening the hold-down clamp and disconnecting the terminals.
- Install the new battery by connecting the positive terminal first, followed by the negative terminal.
- Secure the hold-down clamp to the battery.
Tools Required: Socket set, battery terminal wrench.
Safety Warnings: Always wear gloves and safety goggles when handling batteries.

3. Starter Relay and Cable Inspection

Sub-steps:
- Locate the starter relay in the fuse box and swap it with another relay of the same type to check functionality.
- Visually inspect the starter cables for fraying or damage.
- Ensure all connections are secure and free from corrosion.
Tools Required: None for visual inspection; may need a relay puller for swapping relays.

4. Starter Replacement (if necessary)

Sub-steps:
- If the starter is determined to be faulty, disconnect the battery.
- Remove the electrical connections from the starter motor.
- Unbolt the starter from its mounting using a socket set.
- Install the new starter by reversing the removal process, ensuring all connections are secure.
Tools Required: Socket set, torque wrench.
Safety Warnings: Disconnect the battery before working on electrical components to avoid shorts.
