No injector pulse Help

[Ford Falcon XR6]

Hi everyone i've gone to fire up the v8 in my au for the first time today and it would crank but not start. I've checked the following
Leads have spark
I have power at injectors when ignition is on
Fuel rail has pressure
Motor kicks over and will run when i spray fuel into intake

My tests tell me that for some reason the ecu is not switching the grounds to the injectors. Since i have sprak that would rule out faulty CKP (Crank) and CMP (Cam) sensors correct ?? I'm thinking the ecu i have maybe a dud thought i'd get your thoughts

Cheers
