Solution

1. Preparation

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

2. Battery Inspection

Tools Required: Multimeter, wire brush, socket set
Clean battery terminals with a wire brush if corrosion is present.
Tighten any loose connections at the battery terminals.
Reconnect the negative terminal of the battery.

3. Starter Motor Testing

Tools Required: Jumper cables, multimeter
Locate the starter motor, usually at the rear of the engine near the transmission.
Disconnect the electrical connector from the starter motor.
Use jumper cables to connect the starter motor directly to the battery. If the starter engages and the engine cranks, the starter is functional.

4. Ignition Switch Check

Tools Required: Multimeter, screwdriver
Remove the steering column cover to access the ignition switch.
Use a multimeter to check for continuity across the ignition switch terminals when the key is turned to the start position.
Replace the ignition switch if there is no continuity.

5. Reassemble and Test

Reassemble any removed components and reconnect the battery.
Ensure all connections are secure and components are properly installed.
