Solution

1. Preparation

Ensure the vehicle is in park or neutral and the parking brake is engaged.
Disconnect the negative battery terminal to prevent electrical shock.

2. Battery Replacement (if needed)

Tools Required: Socket set, battery terminal wrench
Remove the negative terminal first, then the positive terminal from the battery.
Unbolt the battery hold-down clamp and carefully lift the battery out.
Place the new battery into the battery tray and secure it with the hold-down clamp.
Connect the positive terminal followed by the negative terminal.

3. Starter Replacement (if needed)

Tools Required: Socket set, torque wrench, extension bars
Remove any components obstructing access to the starter, such as the air intake duct or engine cover.
Disconnect the electrical connectors from the starter, noting their positions.
Unbolt the starter from the engine block using the socket set.
Install the new starter by reversing the removal steps, ensuring all bolts are torqued to manufacturer specifications (typically around 15-20 ft-lbs).
Reconnect the electrical connectors to the starter.

4. Testing the Starter Circuit

After replacing the battery or starter, reconnect the negative battery terminal.
Turn the ignition key to start and listen for the starter engaging.
If the starter engages but the engine does not turn over, further investigation of the ignition or fuel system may be necessary.
