Is there any support for ignition switch theory?

You could test the CPS with a volt meter at the nearest connection by back probing or unplugging the connector and probing the CPS side.
When you crank the engine you will get a signal if the CPS is good.
That way your no longer guessing if the CPS is good or not.
Or I believe you can check the CPS signal with an OBDII reader that has a Porsche program.
Like a Durametric or Foxwell
Threaded Mode
