Solution

1. Preparation

Gather tools: multimeter, socket set, wrench set, and screwdrivers.
Ensure the vehicle is in park (or neutral) and the parking brake is engaged.

2. Battery Check

Sub-steps:
- Disconnect the negative terminal of the battery to ensure safety.
- Remove the positive terminal and clean any corrosion with a wire brush.
- Reconnect the positive terminal followed by the negative terminal.
- Test the battery voltage again; replace if below 12.4 volts.

3. Starter Relay Replacement

Sub-steps:
- Locate the fuse box under the hood and identify the starter relay.
- Remove the starter relay carefully.
- Replace it with a known good relay from another circuit.
- Re-test the ignition system.

4. Ignition Switch Inspection

Sub-steps:
- Remove the steering column cover to access the ignition switch.
- Disconnect the harness from the ignition switch.
- Use a multimeter to test for continuity when turning the key to the start position.
- If there is no continuity, replace the ignition switch.

5. Starter Motor Inspection

Sub-steps:
- Locate the starter motor, usually mounted on the engine block.
- Disconnect the wiring harness and the battery connection to the starter.
- Remove the mounting bolts and take out the starter motor.
- Inspect for damage; replace the starter if necessary.
