Solution

1. Preparation

Ensure the vehicle is parked on a flat surface.
Disconnect the negative terminal of the battery to ensure safety.
Gather necessary tools: multimeter, socket set, OBD-II scanner, jumper wire.

2. Battery Inspection

Inspect the battery terminals for corrosion and clean if necessary using a wire brush.
Tighten any loose connections securely.
If the battery voltage is low, jump-start the vehicle or replace the battery if it fails to hold charge.

3. Starter Motor Testing

Locate the starter motor, which is usually mounted on the transmission bell housing.
Disconnect the electrical connector from the starter motor.
Use a jumper wire to connect the positive terminal of the battery directly to the starter motor terminal.
If the starter engages, it may need replacement.

4. Fuse and Relay Check

Locate the fuse box and check fuses related to the starting system, typically labeled as "Starter" or "Ignition."
Replace any blown fuses with the correct amperage.
Check the starter relay by swapping it with another relay of the same type in the fuse box.

5. Final Steps

Reconnect the negative battery terminal.
Start the vehicle to check if the issue is resolved.
If the vehicle still does not start, further investigation into the ignition switch or wiring may be necessary.
