Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative terminal of the battery to avoid any electrical shorts.

2. Clean Battery Terminals

Use a wire brush to clean corroded battery terminals.
Reconnect the terminals securely and check for tightness.

3. Test and Replace Battery (if necessary)

Use a multimeter to measure battery voltage; if below 12.4 volts, charge or replace the battery.
If replacing, remove the old battery by:
1. Disconnecting the negative terminal first, followed by the positive terminal.
2. Removing any hold-down brackets.
3. Installing the new battery in reverse order, ensuring terminals are connected securely.

4. Inspect and Replace Starter Motor (if necessary)

If the starter motor is suspected to be faulty, proceed with its replacement:
1. Disconnect the battery again.
2. Remove any engine covers if obstructing access to the starter.
3. Disconnect the electrical connectors and mounting bolts from the starter.
4. Install the new starter by reversing the removal steps, ensuring all connections are secure.

5. Reconnect Battery and Test

Reconnect the negative terminal of the battery.
Start the vehicle to check if the issue is resolved.
