Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative terminal of the battery to ensure safety.
Ensure the vehicle is in park or neutral with the parking brake engaged.

2. Battery Inspection and Replacement

Check Battery Condition
- Use a multimeter to measure voltage. If below 12.4 volts, recharge or replace the battery.
- Tools Required: Multimeter, battery charger
Clean Battery Terminals
- Remove the battery terminals (negative first, then positive).
- Clean the terminals and cable ends with a wire brush and a mixture of baking soda and water. Rinse and dry thoroughly.
- Reconnect the terminals securely (positive first, then negative).

3. Starter Motor Inspection

Remove Starter Motor
- Disconnect the wiring harness and battery cable from the starter motor.
- Remove the starter motor mounting bolts using a socket set.
- Carefully take out the starter motor from its location.
- Tools Required: Socket set, wrench
Test Starter Operation
- Use jumper cables to connect the starter motor directly to a charged battery to see if it engages.
- If it does not engage, replace the starter motor.
- If it does engage, inspect the mounting and electrical connections for any damage.

4. Ignition Switch and Wiring Check

Check 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.
- If there is no continuity, replace the ignition switch.
- Tools Required: Multimeter, screwdriver

5. Reassemble and Test

Reinstall the starter motor and secure all connections.
Reconnect the negative battery terminal.
Perform a test start to check if the engine turns over.
