Vy dash install and car won't start

[Zlimes]

Just completed a full VT- VY dash conversion, swapping out dash loom, engine bay loom, ECU & BCM both matched to a key head ((I send ecu away and got flashed and vats removed)). Everything is working but it just wont start It comes up with "Check Engine" in the display window, I can hear the fuel pump prime, the immobiliser light goes out, it will crank but not fire, no spark. The ECU & BCM came as a matched set, I have checked all earths & power at ECU. all seems good, anyone got any ideas where to go next? my VT does have ABS module left vt) Car was running perfect before this conversion, any help at all muchly appreciated


Note
Check for spark no sparking
All relays is getting power
Pump priming
Dfi and coils
New leads and spark
And oil
And new fuel filter
