Has been sitting in storage last 45 days, last time started with difficulty but never any starting problems prior to this, has 89k. Fuel relay appears to be clicking so I'm thinking it's electrical rather than fuel, battery is rock solid, just will not fire at all, one odd thing though... The tach bounces around erratically while cranking from 500 to 1K rpm with no rhyme or reason so I'm guessing OVP first based on that. Next logical candidates might be MAF/MAS or maybe CPS (just had one go out on my 211). Big problem is no access to do normal trouble shooting without towing the car, so hoping for a quick lucky fix without throwing a ton of different part$ at it. Anyone else have similar experiences with their Cabriolet or M104?
