3
Test the Starter Motor: Use a multimeter to check for proper voltage at the starter’s positive terminal when the key is turned to the start position.
4
Scan for Error Codes: Use an OBD-II scanner to check for any diagnostic trouble codes (DTCs) related to the starting system.
5
Inspect the Ignition Switch: Check the ignition switch operation for continuity using a multimeter.
6
Check Fuses: Inspect relevant fuses in the fuse box that may affect the starting system.
