Solution

1. Preparation

Ensure the vehicle is in park or neutral and the parking brake is engaged.
Gather tools and necessary parts.
Disconnect the negative battery terminal to avoid electrical shock.

2. Check and Clean Battery Connections

Sub-steps:
- Remove the positive battery terminal, followed by the negative terminal.
- Inspect for corrosion; clean terminals using a wire brush and a mixture of baking soda and water if necessary.
- Reconnect the terminals securely, attaching the negative terminal first.

3. Test/Replace the Battery

Sub-steps:
- If the battery voltage is below 12.4 volts, charge the battery with a battery charger.
- If the battery fails to hold a charge, replace it with a new one (ensure it matches specifications: Group size, CCA rating).
- After installing a new battery, reconnect the terminals.

4. Inspect and Replace Starter Motor

Sub-steps:
- Remove any components obstructing access to the starter motor.
- Disconnect the wiring harness from the starter motor and remove the mounting bolts using a socket set.
- Install the new starter motor in reverse order, ensuring all connections are secure and torqued to manufacturer specifications.

5. Check Ignition Switch

Sub-steps:
- Remove the steering column cover to access the ignition switch.
- Test the ignition switch with a multimeter to ensure it is sending the proper signals when turned.
- Replace the ignition switch if it is faulty.
