On the Starter Solenoid are 2 yellow wires: One is coming from the ignition lock and the other goes to the TTS located on the left rear chain cover.
Both these wires get power during cranking.
So, climb under and make sure the 2 yellow wires are connected on the Solenoid.
Next, have someone crank the engine while you check the power supply to the TTS; it should have power during cranking but be aware that the TTS cuts out the CSV after a few seconds during cold-start.
The CSV is situated behind the throttle body and hard to reach; in fact, it's a PITA to get to.
The reason why the TTS cuts off power to the CSV is that it should only energize for a few seconds during cold-start. When the engine is warm, the CSV doesn't get energized.

Any Porsche Mechanic should be able to find the problem; try someone else.
Wait for the Bentley; one big error in it is the direction of rotation for the distributor: It is ccw, NOT cw; make a note of that.
