Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is in a safe, well-ventilated area.
Disconnect the negative battery terminal to prevent electrical shock.

2. Battery Inspection

Reconnect the battery terminal if removed.
Clean battery terminals with a wire brush to remove corrosion.
Tighten the battery connections securely.
If the battery is weak (below 12.4 volts), jump-start the vehicle or replace the battery if necessary.

3. Starter Motor Test

Locate the starter motor (usually near the engine block).
Disconnect the wiring harness from the starter motor.
Use a jumper wire to connect the positive terminal of the battery to the starter motor terminal.
If the starter engages and the engine cranks, the starter motor is likely faulty and needs replacement.

4. Fuse Check

Locate the fuse box, typically under the dashboard or engine compartment.
Use the fuse puller tool to check the fuses related to the starting system.
Replace any blown fuses with the exact amperage rating as listed in the owner’s manual.

5. Replace the Starter Motor (if necessary)

If the starter is faulty, remove the bolts securing the starter motor.
Disconnect the wiring harness.
Install the new starter motor, reconnect the wiring, and secure it with the bolts.
Reconnect the negative battery terminal.
