Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is in park (automatic) or neutral (manual) with the parking brake engaged.
Disconnect the negative battery terminal to prevent electrical shock.

2. Inspect and Clean Battery Terminals

Remove the positive (+) and negative (-) battery cables.
Clean the terminals and cable ends using a wire brush or terminal cleaner.
Reconnect the cables securely, starting with the positive terminal followed by the negative terminal.

3. Test and Replace the Battery (if necessary)

Reconnect the negative terminal and test the battery voltage using a multimeter.
If the voltage is below 12.4 volts, consider replacing the battery. To replace:
1. Remove the battery hold-down bracket using a socket set.
2. Lift out the old battery and place the new battery in the tray.
3. Reattach the hold-down bracket.
4. Reconnect the cables, ensuring proper polarity (positive first).

4. Check and Replace Starter Relay

Locate the fuse box and identify the starter relay.
Remove the relay and inspect for damage.
Replace with a new relay if necessary.

5. Test and Replace the Starter Motor (if necessary)

Disconnect the starter motor electrical connections.
Remove the starter mounting bolts using a socket set.
Carefully pull the starter out of the engine bay.
Install the new starter by reversing the removal steps and ensure all connections are secure.
