Default Turbo injector issue... Help

So I was at the end of my build and tried to start car... This is what happened. It cranks over and has spark. It also has fuel at rails fuel pump also primes. I installed versafueler for new injectors. So I started to test things. The injectors test like they should when the are all unplugged. Power on power wires and nothing on pulse wires. But if I plug all the injectors in or even one or two there is power on all wires. Is this the way it should be? Or is something messed up?
I'm lost at this point and now broke a an fitting damn. Can some one shine some light for me?

A ground trigger turns them to open state on the injector itself. The Battery voltage you have on one side of the injector will travel to the other side when it sees power, because it is just a ohms resistance. High or low impedance depending on coil. If it was getting 12v and ground, the injector would open flooding your engine real quick if it was not correct.

So that is correct then. Wonder why I am getting no injector pulse. What runs that? Is it the crank and cam sensors? How do I test those to see if they are working correct? Im sorry for all the dumb questions but I am not the brightest bulb when it comes to testing all these sensors haha.
Thank you for your help!

Did you bypass your versifueler for a second to see if it is the problem?

I didnt do that yet only because I hard wired it in. So all connections are soldered. Whats the best way to go about that? Should I just unhook one injector from the box and connect it the way it was from factory and hook a noid light up to that one injector clip?

Unhooked one of the injector wires going to versafueler and looped it back together like factory. Used noid light to check and there was the problem. Sending it to Jeff at versafueler to get repaired.
