Solution

1. Preparation

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

2. Battery Inspection and Replacement

Inspect Battery:
- Remove the battery from the vehicle using a socket set.
- Check for any signs of physical damage or swelling.
Replace Battery:
- If the battery is faulty or undercharged, replace it with a new one (ensure it meets manufacturer specifications).
- Reinstall the battery, connecting the positive terminal first, followed by the negative terminal.
- Torque battery terminals to manufacturer specifications (typically around 10-15 ft-lbs).

3. Starter Motor Inspection

Inspect Starter Motor:
- Locate the starter motor and visually inspect for loose connections or damage.
Test Starter Motor:
- If necessary, remove the starter motor for bench testing.
- Use a multimeter to test the solenoid activation and motor function.
Replace Starter Motor:
- If the starter is faulty, replace it with a new one, ensuring proper alignment and secure mounting.
- Torque mounting bolts to manufacturer specifications (typically around 30-40 ft-lbs).

4. Reconnect Battery and Test

Reconnect the negative terminal of the battery.
Attempt to start the vehicle to check if the issue has been resolved.
