1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is in a safe, level area and the engine is off.
Disconnect the negative battery terminal to prevent electrical shock.

2. Inspect and Clean Battery Connections

Remove the positive (+) and negative (-) battery cables.
- Tools Required: Socket set
Clean the terminals and cable ends using a wire brush.
Reconnect the battery cables securely.

3. Battery Replacement (if necessary)

If the battery voltage is below 12.4 volts, proceed to replace it.
Remove the old battery from the battery tray.
- Tools Required: Socket set
Install the new battery, ensuring correct polarity (+ to +, - to -).
Secure the battery with the retaining clamp.

4. Starter Relay and Fuse Check

Access the fuse box and remove the starter relay.
- Tools Required: Fuse puller or pliers
Inspect the starter relay for any signs of damage; replace if faulty.
Check the fuses related to the starting system and replace any that are blown.

5. Testing the Starter Motor

If the issue persists, test the starter motor directly by applying voltage to it.
- Tools Required: Jumper cables
If the starter engages and the engine cranks, the starter may need to be replaced.
