Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the negative battery terminal to prevent electric shock.

2. Battery Inspection and Replacement

Inspect Battery:
- Clean any corrosion from battery terminals using a wire brush.
- Tighten battery connections if loose.
Replace Battery (if necessary):
- Remove the battery hold-down bracket using a socket set.
- Disconnect the positive terminal first, followed by the negative terminal.
- Install the new battery by connecting the positive terminal first, then the negative terminal.
- Secure the battery with the hold-down bracket.

3. Starter Inspection

Remove Starter:
- Disconnect the negative battery terminal again for safety.
- Remove any components obstructing starter access (like the intake duct or heat shield).
- Unbolt the starter motor using a socket set and carefully remove it from its mounting.
Test Starter:
- Bench test the starter with a battery and jumper cables to see if it spins.
Replace Starter (if necessary):
- If the starter fails the bench test, replace it with a new or refurbished unit.
- Reinstall the starter motor and ensure all bolts are torqued to manufacturer's specifications.

4. Verify Connections

Check all wiring harnesses connected to the starter and battery for damage.
Ensure that the ground connection from the engine to the chassis is clean and secure.
