Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is in park (or neutral) and the parking brake is engaged.

2. Battery Inspection

Sub-steps:
1. Disconnect the negative battery terminal using a wrench.
2. Clean any corrosion from the battery terminals using a wire brush.
3. Reconnect the battery terminal securely.

3. Test Battery Voltage

Sub-steps:
1. Use a multimeter to measure the voltage across the battery terminals.
2. If the voltage is low (below 12.6 volts), charge the battery or replace it if necessary.

4. Starter Relay and Fuse Check

Sub-steps:
1. Locate the fuse box and identify the starter relay and fuse.
2. Remove the starter relay and visually inspect it for damage.
3. Replace any blown fuses and install a new starter relay if needed.

5. Inspect Ignition Switch

Sub-steps:
1. Remove the steering column cover to access the ignition switch.
2. Check the ignition switch for continuity using a multimeter.
3. Replace the ignition switch if it fails the continuity test.

6. Starter Motor Inspection

Sub-steps:
1. If the previous steps do not resolve the issue, access the starter motor.
2. Inspect the wiring and connectors for any signs of damage.
3. Test the starter motor by applying direct battery voltage to it; if it does not engage, replace the starter motor.
