you need to check for power to the little wire at the starter when the motor is cranking to verify if there is a supply issue of electric or a bad starter

starts at the ignition switch and goes through the park neutral switch.

check each for power before throwing parts at it.

Good afternoon,

Check this guide and see if you can give me any more information. You need to check for fuel and spark to see which system is not working.
