Diagnostic Steps

1
Check the battery voltage using a multimeter; it should read above 12.4 volts.
2
Inspect battery terminals and cables for corrosion or loose connections.
3
Try jump-starting the vehicle with jumper cables or a jump starter.
4
Test the starter motor by bypassing the ignition circuit (use a remote starter switch).
5
Scan for any diagnostic trouble codes (DTCs) using an OBD-II scanner.
6
Inspect fuses related to the starting system.
