Solution

1. Preparation

Gather necessary tools and equipment.
Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Battery Inspection

Sub-steps:
1. Clean the battery terminals using a wire brush and baking soda solution if corrosion is present.
2. Tighten any loose connections on the battery terminals.
3. Reconnect the negative battery terminal.

3. Starter Motor Testing

Sub-steps:
1. Locate the starter motor, usually found on the lower side of the engine near the transmission.
2. Disconnect the wiring harness from the starter motor.
3. Use jumper cables to connect the starter motor directly to the battery, ensuring proper polarity.
4. If the starter engages and the engine turns over, replace the starter motor.
5. If it does not engage, further inspection of the wiring and ignition switch is necessary.

4. Ignition Switch Inspection

Sub-steps:
1. Remove the steering column cover to access the ignition switch.
2. Disconnect the wiring harness from the ignition switch.
3. Use a multimeter to check for continuity across the switch terminals when the key is turned.
4. Replace the ignition switch if there is no continuity.

5. Reassembly

After completing the necessary repairs, reassemble any components that were removed.
Ensure all connections are secure and free of corrosion.
