When i turn the key to the “ON” position the starter cranks until i turn the key back to off. Any help would be greatly appreciated! Also the car is computer deleted so all I’m working with is the C100.

Trace the voltage back from the starter. Check for power on the purple wire on the small terminal of the starter and work backwards and see how it's getting energized. Possibly the ignition switch or the actuator for the ignition switch is causing it to energize in the run position.

It seems the starter is just obeying commands.

Maybe your ignition switch pull rod needs adjustment.

Good luck with the troubleshooting, keep us updated on what you find.

Need some context here. Did this issue occur right after you did the computer delete?

Just for grins put the shifter in drive and turn the key and see if the starter turns over. If it does then somehow it's energizing it past the NS switch. If not then I bet it's in the ignition switch or the timing of the rack for the switch.
