no power to fuel injectors

i am currently finishing up my build and hooking everything up. I tested everything out and seems good. The car does turn over but doesnt seem to be getting fuel.I tested all the injectors on a 12v battery and they all click. Then i tested the injector wires on the wiring harness and there is no power to them. The car does have an fjo driver box and pfc. everything else works except the injectors due to no power. Am I missing something or did I not connect something..?>

The power for the injectors comes from a connector inside the cabin near the ECU. Did you have your engine harness out for some reason?

yes i did...i got a single turbo harness...everything looks connected to the pfc...there is a blue connecter thats is sitting open but i dont see another plug for it to go to. I sprayed starter fluid into the intake and the car did start so i know for sure its the injectors not even powering up. The fuel pressure is at about 40psi so i know I have good fuel pressure..i used a test light to see if any voltage is getting to them and nothing...i checked all the fuses and they are all good

There is another plug, that connects the dash harness to the engine harness. This is where the injectors get the power from. If you reach up behind the A/C evaporator you will find the plug, where the engine harness runs up along the inner firewall

So now the injectors are seeing 12V? You said it started with starter fluid, so the ignition should not be the issue. More likely it is an issue with the FJO injector driver or the installation of it.

The number one sign that a portion of the ignition system is bad ......No spark

Check your CAS connectors, white on top, gray on the bottom.
