Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is in a safe and stable position, preferably on a level surface.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Clean Battery Connections

Remove the positive and negative battery cables.
Clean the terminals and cable ends with a wire brush until shiny.
Reconnect the battery cables securely, starting with the positive terminal, then the negative.

3. Replace the Battery (if necessary)

If the battery voltage is below 12.4 volts, it may need replacement.
Remove the battery hold-down bracket using a socket set.
Carefully lift the old battery out of the tray.
Place the new battery in the tray and secure it with the hold-down bracket.
Reconnect the battery terminals in the correct order.

4. Inspect and Replace the Starter Motor (if necessary)

Remove any components obstructing access to the starter motor (e.g., intake ducts).
Disconnect the electrical connectors from the starter motor.
Remove the starter motor mounting bolts using a socket set.
Replace with a new starter motor, ensuring it is properly aligned.
Reconnect the electrical connectors and secure the motor with mounting bolts.

5. Check the Starter Relay and Fuses

Locate the fuse box and check the starter relay for continuity.
If the relay is faulty, replace it with a new one.
Inspect and replace any blown fuses related to the starting system.
