I really suspect a wiring issue (broken wires, grounds, etc.).
I'm assuming the battery was disconnected while the injector wiring was worked on?

Tested everything as you suggested. Yes there's 12V at every injector on the B-R wire and I believe I just figured out why I wasn't getting 12V at the ECM. I went off of the original picture I posted to determine which pins but just realized there are more plugs in the picture than there are on my actual ECM. I went back to the service manual and found a wiring diagram from the injectors to the ECM, finding the pins with the wire colors given on the wiring diagram and I am getting the correct 12V at the injector pins ECM as well. ����
Yes the battery was disconnected when the work was being done.
