Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is in "Park" (automatic) or "Neutral" (manual).
Disconnect the negative battery cable to avoid electrical shocks.

2. Inspect Battery Connections

Remove the battery terminals, starting with the negative terminal.
Clean any corrosion from the terminals using a wire brush or terminal cleaner.
Reattach the terminals securely, ensuring tight connections.

3. Test/Replace the Battery

Reconnect the negative battery terminal.
If the battery voltage was low, charge it or replace it if it fails to hold a charge.
If jump-starting the vehicle works, the battery may need replacement.

4. Check the Starter Motor

Locate the starter motor; typically found near the transmission bell housing.
Check the wiring harness for loose connections or damage.
If necessary, remove the starter motor for testing at an auto parts store or replace it if it's faulty.

5. Inspect the Ignition System

If the vehicle still does not start, check the ignition switch and its wiring for faults.
Test the ignition relay to ensure it is functioning; replace if defective.
