Do you mean you can't crank the starter from the ignition switch but are able to crank the starter by means of bypassing the ignition switch?

Is this an auto or manual transmisison?

Faulty ignition or park and neutral position switch are possible causes.

Try shifting to N and see if you can crank.

Yes. You need to confirm that it is correctly adjusted.
If dash indicator lights are working, ensure the P indicator lights up when gear shift is in position.

If lights work ok, you would need to do troubleshooting with the wiring circuit. You would need a test light or a DVOM. Have you checked the starter relay?
