The history:

Ignition switch: replaced.
Clutch switch: checked, appears to be going in and out and clicking accordingly.
Fuses: all appear good.
Relays: seem okay. switched out relay with same #, still no crank.
Immobilizer: opened box under seat; no obvious sign of any damage of any sort.
Starter: tested, spins fast.
Solenoid/Starter: Cranks engine hard and fast.
Analyzer readout: no problem codes.
Key: appears good; "capsule" inside appears fine.
Sorry I missed that part. Sure sounds like an immobilizer problem.

Bypassing the switch will at least disable your cruise contol. Bypass it to test or use a VOM, if bad replace it.

I assume this problem started BEFORE you replaced the ignition switch?

Yes, the problem started before i replaced the switch. The switch was very sticky and stubborn, so I was hopeful that this was the problem. An fyi for other readers, while Porsche would only sell me the whole assembly for $160, Audi sold me just the switch for $40.

A silly question I imagine, but can the immobilizer be tested? can it be by passed? Or am I stuck going to the dealer on this one?

Other than reading the codes, which you say you have none, its off to someone that has the correct Porsche tester.

My dealer reprogrammed my key for free, when my immobilizer threw a code saying the transponder code was wrong (new key).

Well, then, if it's not my clutch switch, I suppose I'm off to the dealer to handle this. Can independent Porsche repair places reprogram keys and immobilizers, or is this strictly a dealer function ?

Only the dealer has one of the codes for your car.

I never noticed, shows how much I use the cruise control.
