New engine wont start, 0% injector duty while cranking???

evening all
I have just rebuilt my FD3 engine and converted to single turbo, I am still using the APexi PFC that i was using before it blew a tip when running the twins. I have put bigger injectors and modified the loom accordingly. The commander is displaying revs, vacume, TPS and temps and I have spark but it just wont fire. I have fuel pressure.

I am baffled. I understand that if i have spark the white crank angle sensor must be working?

Any suggestions gratefully received....
