Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the negative battery terminal to prevent any electrical shorts.

2. Inspect and Clean Battery Connections

Tools Required: Wire brush, battery cleaner, socket set.
Remove the positive (+) and negative (-) battery terminals using a socket set.
Clean the terminals and battery posts with a wire brush and battery cleaner.
Reconnect the terminals, ensuring they are tight and secure.

3. Check and Replace the Battery (if necessary)

Tools Required: Multimeter, socket set.
If the battery voltage is below 12.4 volts, consider replacing the battery.
To replace, remove the old battery using a socket set and install the new battery in reverse order, ensuring the terminals are connected properly.

4. Inspect the Starter Motor

Tools Required: Multimeter, socket set.
If the starter motor is suspected, remove it by disconnecting electrical connectors and supporting bolts.
Test the starter by connecting it directly to a power source to confirm functionality. If it does not engage, replace the starter motor.

5. Check Fuses and Relays

Tools Required: Fuse puller or pliers.
Locate the fuse box and identify the fuses related to the starting system.
Replace any blown fuses and ensure all relays associated with the starter circuit are functioning.
