Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, vehicle jack, and jack stands.
Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Battery Inspection

Check Voltage:
- Use a multimeter to measure the battery voltage; it should read at least 12.4 volts.
- If low: Charge or replace the battery as necessary.
Inspect Connections:
- Tighten and clean the battery terminals to ensure a good connection.

3. Starter Motor Assessment

Remove Starter Motor:
- Raise the vehicle and secure it on jack stands.
- Disconnect the battery negative terminal.
- Remove the starter motor mounting bolts using a socket set and carefully extract the starter.
Inspect Components:
- Check for physical damage, such as cracks in the casing or worn out gears.
- Test the starter motor with a multimeter to confirm proper function.

4. Ignition Switch and Relay Check

Inspect Ignition Switch:
- Remove the steering column cover.
- Use a multimeter to check for continuity across the switch terminals when turned to the start position.
Test Starter Relay:
- Locate the starter relay in the fuse box.
- Swap it with a similar relay to test functionality.

5. Reinstallation

Reinstall Components:
- Reinstall the starter motor and secure it with the mounting bolts to the specified torque (typically around 15-20 ft-lbs).
