Over fueling cylinder six

I have already replaced all of the injectors and the #6 injectors is constantly pouring fuel into the cylinder

Here's what I posted > 'IF' injector *PULSE* is ok on # 6 .. Replace # 6 fuel injector! .. There must be a problem with the wiring to that injector that's holding injector open! .. Can be confirmed by checking injector on - off pulse signal using a noid light... IF there is no visible wiring damage, It is also possible there is a problem within the ECM injector driver circuit... Recommend obtaining a diagnostic flow chart and wiring diagram plus ECM pin out schematic to test driver circuit... You can also use a very long screwdriver or such to listen to the injector with engine on to see if you hear it clicking.. Listen to another so you'll know what is is supposed to sound like .. Yes I know, injector access is limited but # 6 should be accessible (rear injector on front bank of engine) .. IF unsure how to do the testing, seek qualified hands-on help .. Good luck!
