Solution

1. Preparation

Gather necessary tools.
Ensure the vehicle is in park (or neutral) with the parking brake engaged.
Disconnect the negative battery terminal for safety.

2. Battery Check and Replacement

Check Voltage: If the battery voltage is below 12.4 volts, recharge or replace the battery.
Clean Terminals: If corroded, clean the terminals with a wire brush and a mixture of baking soda and water.
Reconnect: Reconnect the battery terminals securely after cleaning.

3. Starter Motor Inspection

Remove Starter:
- Disconnect the wiring harness from the starter.
- Remove the bolts securing the starter motor to the engine block using a socket set.
Test Starter:
- Use jumper cables to connect the starter directly to the battery. If it does not engage, replace the starter motor.

4. Inspect and Replace Fuses/Relays

Locate Fuse Box: Find the fuse box under the dashboard or hood.
Check Starter Relay: Remove the starter relay and test it with a multimeter. Replace if defective.
Inspect Fuses: Check for blown fuses related to the starting system and replace as necessary.

5. Ignition Switch Testing

Access Ignition Switch: Remove the steering column covers to access the ignition switch.
Test Functionality: Use a multimeter to check continuity across the ignition switch terminals when turned to the start position.
Replace if Necessary: If the switch is faulty, replace it with a new unit.
