Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface.
Disconnect the negative battery terminal to ensure safety.

2. Battery Inspection

Tools Required: Wrench, multimeter
Inspect battery terminals for corrosion; clean with a wire brush if necessary.
Ensure terminals are securely tightened.
Use the multimeter to check the voltage; if below 12.4 volts, charge or replace the battery.

3. Fuses and Wiring Check

Tools Required: Fuse puller, multimeter
Locate the fuse box and check for any blown fuses related to the starting system.
Replace any blown fuses with the correct amperage.
Inspect wiring harness for any visible damage or loose connections.

4. Starter Motor Testing

Tools Required: Multimeter, jumper cables
Disconnect the starter motor electrical connector.
Use jumper cables to apply direct power to the starter; if it does not engage, replace the starter motor.
If the starter engages, check for issues with the ignition switch or relay.

5. Reassembly

Reconnect all electrical connections and terminals.
Ensure all tools are removed from the engine bay.
Reconnect the negative battery terminal.
