Solution

1. Preparation

Ensure the vehicle is in park (automatic) or neutral (manual).
Disconnect the battery by removing the negative terminal first.
Gather necessary tools: multimeter, socket set, jumper cables, and possibly a replacement battery or starter.

2. Battery Inspection and Replacement

Check Battery Condition
- If the battery voltage is below 12.4 volts, charge the battery fully or replace it.
Clean Battery Terminals
- Remove the terminals (negative first, then positive) and clean off any corrosion with a mixture of baking soda and water.
- Reconnect terminals securely.

3. Starter Motor and Solenoid Inspection

Remove Starter Motor
- Disconnect the wiring harness from the starter and remove the mounting bolts using a socket set.
- Carefully extract the starter motor from its housing.
Test Starter Motor
- Use a multimeter to check for continuity and resistance across the starter terminals.
- If the starter is faulty, replace it.

4. Ignition Switch Check

Inspect Ignition Switch
- Remove the steering column cover to access the ignition switch.
- Use a multimeter to check for continuity when the key is turned to the start position.
- Replace the ignition switch if defective.
