Injector issues

What would cause an injector harness to get 12+ volts to the pigtail when unplugged from the injector, but only get .05 volts when plugged into the injector? I’ve been chasing this problem for a couple months now with no luck. 2 ECUs, 2 whole wiring harnesses, 3 injectors, 2 fuel pumps, etc.. someone please help, I’m about to rip my hair out 😩 the injector is getting plenty of fuel delivered to it but is not firing.

im thinking maybe one of the sensors is crazy and is messing with the quad or maybe its heat temp sensor it is related to how much the injector should spray, im having kind of the same issue my injector is spraying too much fuel still haven't figured out what the issue is though
