OK, I accidentally sprayed water inside the FICM one day cleaning the engine off. It was fried so bad it had to be replaced. I put the new one on and I have codes for the crank position and cam position output circuits open. I went ahead and replaced both sensors just to do it for a quick and easy fix. Well, that wasn't the problem. With my scanner I checked to for "sync", and with the engine cranking it "synced" together. Has anyone else had the output circuit codes before or can someone point me in the right direction possibly with ohm readings for the circuits. Thanks.

Off hand I would check your FICM connections they can be problematic to properly seat.
