Solution

1. Preparation

Gather Tools: OBD-II scanner, multimeter, socket set, torque wrench, and safety gloves.
Safety Precautions: Disconnect the negative battery terminal to prevent electrical shock.

2. Remove the Starter Motor

Locate Starter: Identify the starter motor, typically found near the engine's transmission housing.
Disconnect Wiring: Remove the electrical connections from the starter motor, including the main power cable and signal wire.
Unbolt Starter: Use a socket set to remove the bolts securing the starter motor to the engine block.
Carefully Extract Starter: Gently pull the starter motor out of its housing.

3. Inspect and Test the Starter

Visual Inspection: Check for any signs of damage, such as burnt contacts or a cracked casing.
Test Starter Motor: Using a bench test, connect the starter motor to a fully charged battery to determine if it engages and spins properly.
Replace if Necessary: If the starter fails the test, replace it with a new or refurbished unit.

4. Install New Starter Motor

Position New Starter: Place the new starter motor into the housing, aligning it with the mounting holes.
Secure Starter: Tighten the bolts to the manufacturer's specified torque (typically around 20-25 ft-lbs).
Reconnect Wiring: Reattach the electrical connections to the starter, ensuring a secure fit.

5. Final Steps

Reconnect Battery: Reattach the negative battery terminal.
Test Start: Turn the ignition key to check if the engine starts successfully.
