Ingition issue

Problem is coil 3 is not firing (I've replaced coil already, pervious coil had same issue). Resultingly we are running horriblely (barely at all), low idle, no power, only ~12" of vaccum. I'm thinking the Crank Position Sensor, is not signalling the the Ingintion Module to fire Coil 3 (hope at least that its not the ICM). By my understanding the Crank sensor signals which coil to fire and the Cam Senor say which plug is hot.

I've check the voltage and on Coil 1 and 2 there is a rise as RPMs go up but C3 is steady (A/C).

Currently only codes are 217 (coil 3 not fireing).

If all else fails get a bigger hammer!
