I believe there is a purple wire that goes to the starter. You can search and confirm that. Once you find the wire that goes to the starter you can determine if you have current to the starter. If you do you can eliminate the VATS and the clutch switch.

If no current on the starter wire, then you have VATS or clutch starter issue. Since you replaced parts related to the clutch, your problem could point to the clutch switch.

You won't know until you determine if you have current to the starter...

Good luck...
