Injector controller?
Got a problem with one of the injectors on my 3vze, it’s constantly open. Wondering if the injectors are controlled by the ecu or a seperate controller?

You don't mention the year of your truck, and it matters.
Having said that, as far as I know, the ECU controls the injectors. BUT: A single injector remaining full open all the time sounds to ME, for what that's worth, that the injector is bad, not the controller.
Have you unplugged the electric connector to the injector in question, and checked to see if it's still wide open? That would tell the tale of whether it's the injector, or it's controller. If it remains wide open with the electric connector unplugged, it's the injector, no question.
Good luck, and keep us up to date

i've looked at your other threads on this. not that i'm an expert by any stretch, but it occurred to me a problem in the wiring....like a short or something. ie. perhaps instead the voltage signal pulsing it's remaining a constant feed sans pulsing. just speculating
you've gotten really dynamite/expert input in other threads. give up the idea of the ECM/injector drivers.
