850 won't start
Just got home two days ago from a 2k round trip trip to FL, no problems...850 ran great. This morning I start it to head to work, it starts as normal, runs for about 3 seconds then dies as if I keyed the ignition off. After messing with it for several hours I have yet to get it to run or try to run. It just turns over. Best I can find so far was when I pulled the single wire coming from the ignition coil (between the air box and strut mount) from the distrubutor cap, grounded it, turned the engine over, no spark. I grounded it to several things to make sure, nothing.
Where should I go from here?

By grounding it what do you mean? If it is clipped all the way to ground it won't show spark. The test there is to hold it 1/8" or so off of a ground point and see if it sparks.
Do you have fuel pressure? Is the fuel pump running when you try to start the car? If you listen behind the passenger's side rear seat you should be able to hear the pump run when the key is in position II.

Best of luck, mine did exactly the same. Six months later still havent got it running but havent given up hope yet.
Check for a signal to the fule injectors and check for fault codes in the ECU.
Sounds like the RPM sensor might be faulty.

I swapped out a known working ignition coil from another 850, nothing.
Next step the RPM and Cam sensors.
I have access to 10 or so 850s for parts. Are these sensors something I could pull from another 850 to try or am I better off buying new ones? Like to save some cash, especially since I am not 100% these new parts will fix it.
Thanks for you help =)

Yea, no spark and there is fuel pressure.
