My Porsche will start, but, when put in gear, cuts off. My Porsche mechanic says it has to do with the ORIGINAL alarm system and is doing it to stop it from being stolen. He has tried everything to bypass it, but nothing works. It will start, but then cut off. He has been working on it on and off for a year. What can we do?
