I have had a good run with my 986 and no problems for a good while, but nothing lasts forever... In the last month the car will randomly stall and refuse to start back up for an undefined period of time. When it happens all the lights on the dash will flash on as if the key has just been turned to the on position. The starter will crank the engine happily but there is no ignition happening. This will last for an unknown amount of time (20 min or a day) and then the car will start right up again. Only to stall out later at some unknown point. (15 min or 1 hour). I have hooked the durametric up to it each time and got nothing, except the last time. P1571 fault 39, pointing to the immobilizer. After searching I came upon this thread from 2009, that describes exactly what I am experiencing, but a solution was never posted. http://www.renntech.org/forums/topic/28462-cranks-but-wont-start-help-please/ So to get down to point, I have a few trouble shooting questions and steps I will take next; 1.) The ignition switch has been giving me the traditional issues and it probably needs to be replaced (again). If the electronics in the plastic switch are going bad, could they cause this? Engine stall, clean crank with no start-up? 2.) could the P1571 be attributed to a freak accident during the stall that confused the car since I never got this error before? After I cleared it and cranked it with no start, there were no new fault codes. 3.) Im reading conflicting info on crank position sensors. Will they relay a fault code, or not? 4.) I have tried both keys, ruling out a bad key transmitter. 5.) I will check the immobilizer under the seat, but don't expect any water damage. 6.) I will check all the relays. Sorry for the long winded explanation. If anyone has a history with this, or any insight to #1,#2, or #3, please share.
