Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the negative terminal of the battery to ensure safety while working on electrical components.
Tools Required: Socket set, multimeter, OBD-II scanner.

2. Inspect Battery Connections

Recheck the battery terminals for corrosion or damage.
Clean the terminals with a wire brush if corroded, and ensure a secure fit when reconnecting.
Reconnect the negative terminal and ensure it is tight.

3. Check and Replace Fuses

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Remove any fuses related to the starting system and inspect them visually.
Replace any blown fuses with the same amperage rating.

4. Test Starter Motor

Locate the starter motor, which is usually mounted on the engine near the transmission.
Use a jump wire to bypass the starter solenoid by connecting the positive terminal of the battery directly to the starter terminal.
If the starter engages and the engine cranks, the starter may need replacement.

5. Reconnect and Test

Re-connect the battery terminals securely.
Reconnect any fuses that were removed.
Attempt to start the vehicle again.
