Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is in a safe location, ideally with the battery disconnected.
Tools Required: Multimeter, socket set, screwdrivers, OBD-II scanner, jumper cables.

2. Battery Connection Inspection

Remove the negative terminal from the battery using a wrench.
Clean any corrosion from both battery terminals with a wire brush.
Reconnect the terminals securely, starting with the positive terminal, followed by the negative.

3. Starter Relay Test

Locate the starter relay in the fuse box.
Swap the starter relay with another relay of the same type (e.g., horn or AC relay).
Attempt to start the vehicle. If it starts, replace the faulty relay.

4. Ignition Switch Inspection

Remove the steering column cover to access the ignition switch.
Disconnect the wiring harness from the ignition switch.
Use a multimeter to test for continuity when the key is turned to the start position.
Replace the ignition switch if no continuity is detected.

5. Starter Motor Check

If the vehicle still does not start, locate the starter motor.
Check the connections to the starter motor for tightness and corrosion.
Use a multimeter to test for voltage at the starter motor when the ignition key is turned to the start position.
If there is no voltage, further investigate the wiring or replace the starter motor if necessary.
