Solution

1. Preparation

Gather tools and ensure safety gear is worn.
Disconnect the negative battery terminal to prevent electrical shock.

2. Battery Inspection

Sub-steps:
1. Remove the positive battery terminal (use a 10mm socket).
2. Clean any corrosion on both terminals using a wire brush and a baking soda solution.
3. Reconnect the positive terminal and then the negative terminal, ensuring they are tight.

3. Starter Motor Replacement (if necessary)

Sub-steps:
1. Disconnect the negative battery terminal again.
2. Remove the starter motor (typically located under the engine near the transmission).
  - Use a 12mm socket to remove the mounting bolts.
3. Disconnect the wiring harness from the starter.
4. Install the new starter by reversing the removal steps.
5. Tighten the mounting bolts to the manufacturer’s specification (usually between 20-25 ft-lbs).

4. Testing the System

Sub-steps:
1. Reconnect the negative battery terminal.
2. Turn the ignition key to the "ON" position and listen for the fuel pump.
3. Attempt to start the vehicle.
4. If it starts, monitor for any irregular noises or dashboard warning lights.
