Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is in park (automatic) or neutral (manual).
Disconnect the negative terminal of the battery to prevent electrical shock.

2. Battery Inspection

Sub-steps:
1. Clean the battery terminals using a wire brush.
2. Tighten any loose connections on the battery terminals.
3. If the battery voltage is low, charge or replace the battery as needed.
Tools Required: Wire brush, battery terminal cleaner.

3. Starter Motor Testing

Sub-steps:
1. Reconnect the battery terminal.
2. Use jumper cables to connect a known good battery to the starter motor.
3. If the starter engages and the engine cranks, replace the original battery.
4. If the starter does not engage, replace the starter motor.
Tools Required: Jumper cables, socket set.

4. Relay and Fuse Replacement

Sub-steps:
1. Locate the fuse box and identify the starter relay and associated fuses.
2. Replace any blown fuses with the correct amperage.
3. Swap the starter relay with a known good relay from another circuit, if available.
Tools Required: Fuse puller, socket set.

5. Ignition Switch Inspection

Sub-steps:
1. Remove the steering column cover to access the ignition switch.
2. Test the ignition switch with a multimeter for continuity when turned to the 'start' position.
