Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the negative terminal of the battery for safety.

2. Battery Inspection

Tools Required: Multimeter, battery terminal cleaner
Check battery voltage with the multimeter; it should read 12.4 volts or higher.
Clean any corrosion on the battery terminals using the terminal cleaner.
Reconnect the battery terminals securely.

3. Starter Motor Replacement

Tools Required: Socket set, ratchet, torque wrench
Locate the starter motor, usually found on the lower side of the engine near the transmission.
Remove the electrical connections (note their positions for reinstallation).
Remove the mounting bolts securing the starter motor and carefully extract the starter from its location.
Installation:
- Position the new starter in place.
- Secure it with the mounting bolts and torque them to the manufacturer’s specifications (typically around 30-40 ft-lbs).
- Reconnect the electrical connections to the starter.

4. Ignition Switch Assessment

Tools Required: Screwdriver set
Remove the steering column cover using a screwdriver.
Inspect the ignition switch for wear or damage.
If faulty, replace the ignition switch with a new one, ensuring all connectors are securely attached.

5. Final Assembly

Reinstall any covers or panels removed during the repair.
Reconnect the negative battery terminal.
Start the engine to verify repair.
