Solution

1. Preparation

Gather tools: multimeter, socket set, OBD-II scanner, remote starter switch.
Ensure the car is in park (automatic transmission) or neutral (manual transmission).
Disconnect the battery to prevent any electrical shorts.

2. Battery and Connections

Remove the negative (-) battery terminal, then the positive (+) terminal.
Clean battery terminals and cable ends using a wire brush.
Reconnect the positive (+) terminal first, followed by the negative (-) terminal.
Tighten connections securely.

3. Starter Motor Check

Locate the starter motor under the vehicle.
Disconnect the electrical connector from the starter motor.
Using a remote starter switch, connect the battery positive to the starter terminal and the negative to the starter casing.
If the starter engages, it is functioning properly; if not, replace the starter motor.

4. Ignition Switch Inspection

Remove the steering column cover to access the ignition switch.
Use a multimeter to check for continuity at the ignition switch terminals when the key is turned to the "start" position.
If no continuity is found, replace the ignition switch.

5. Fuel System Verification

Locate the fuel pump fuse in the fuse box and check for continuity.
If the fuse is good, listen for the fuel pump activation when the ignition is turned on.
If the pump does not activate, replace the fuel pump.
