TBI injectors not firing - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I'm in need of some help guys!!

I've got a '93 tbi engine in my '60 c10 and more or less everything works but injectors are not firing. Engine ran when removed from donor car.
I'm thinking there is a trigger signal I'm missing or something really simple but at, I'm a little lost!! Could it be that the ecu needs a signal from the fuel pump to fire the injectors?
I can't find any pinout diagrams for these ecu's so not sure about the fuel pump signal !!

Any help is welcome!
