Unfortunately, you may need to find a different shop. Or maybe the "shop" needs to give you some more info, such as "how did they determine that there was no power to the injectors?" IOW, what was the actual test they did?
As I think I wrote previously, it is not too hard to simply apply 12V to an injector to determine if it is working.
A critical piece of information we need to know is whether this ECU was working before the transplant?
