Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is in a safe environment with the ignition off.
Disconnect the battery negative terminal to prevent accidental short circuits.

2. Battery Inspection

Tools Required: Multimeter
Check battery connections for corrosion. Clean with a wire brush if necessary.
Reconnect the battery terminals securely.
If the battery voltage is low, charge or replace it.

3. Starter Relay and Fuse Check

Tools Required: Fuse puller or needle-nose pliers
Inspect and replace any blown fuses related to the starting system.
Swap the starter relay with a similar relay in the fuse box to test functionality.

4. Starter Motor Inspection

Tools Required: Socket set, torque wrench
Locate the starter motor, typically mounted on the lower side of the engine.
Disconnect the wiring harness and positive cable from the starter.
Remove the starter mounting bolts and take out the starter motor.
Inspect for any damage or wear, and test it with a bench test if possible.
If the starter is faulty, replace it with a new unit.

5. Final Assembly

Reinstall the starter motor and torque the mounting bolts to the manufacturer's specifications.
Reconnect the wiring harness and positive cable.
Reconnect the battery negative terminal.
