FiTech EFI system

Haven't read thru this whole thread, but I recently purchased the FiTech 600 HP version from Pace, who by the way were really great to work with, having installed the unit without timing control just to get a feel for it has been a bit challenging, but I am making progress. So yesterday I decided to get ambitious and enable timing control. Following the manual, I rotated the engine to my desired initial timing 16* and locked out my distributor, installed and phased my rotor clockwise to 10*, changed the wiring on my MSD 6AL then tried to start the car, won't start. It does try to fire, but coughs thru the throttle body. Obviously something is not right with the timing. I went back and double checked everything and followed the directions to the T, even rotating my engine to 10* initial and phasing the rotor the same way, still nothing.

Looking for some help here from anyone that may have had the same experience and how they resolved it. I sent an email to FiTech, but they are little slow in responding and I want to get his addressed sooner than later.
