I thought the VATS was in the anti-theft system and in the factory wiring migh shut off fuel pump and definitely shut down injector firing but NOT in the start circuit.

Motor not continuing to run I would lean towards VATS, but no starter turn over makes me think anti-theft relay.

Find the starter relay in the interior wiring. Of the top of my head I think the heavy purple wire goes to the starter solenoid. Check voltages at that relay socket.
