FC not starting - no spark

Hi guys
Motor has been put into an FC and the vehicle doesnt wanna start
-Car is stock, running stock computer etc
-Timing is correct and am getting fuel
-Have checked coils, am getting power to the coils, used a multimeter checked plug with black/yellow wire on L1 coil, 12v present with ign on.
-When vehicle is cranking, i have removed L1 spark plug lead and earthed it out but im getting no spark. Also i have noticed that the tacho does not 'bounce' when cranking, which would indicate that its not getting a signal to/from the trailing coils.
-Removed CAS with ign on and spun the small gear gear and can get spark happening with a spark plug lead removed and earthed and can hear fuel system priming and injectors pulsing.
-Have tried another AFM, still no go

-One thing i noticed is that when we put the ignition on, i DONT hear any fuel systems priming on this car but on my FC i can hear the fuel system priming for 5 or so seconds before i go to start it. At the same time i do realise that the fuel pump activates when the CAS is spinning.
-Have removed upper intake manifold numerous times and checked all earths and they all look clean and secure. Can't see any wires floating around.
So yeah thats where we're at, open to ANY suggestion now

Thanks ppl

Andrew
