Not sure but perhaps the wires to the injector is shorting somewhere to effectively apply a signal to that particular injector. Form what i understand one side of the injector is a constant 12 V and the PCM grounds the other side when it wants the injector to activate. Perhaps the ground side has shorted to something. It is possible that the PCM input has latched low as well.

We it certainly could be. I can't really say for sure with the limited information here. I would check obvious things like frayed wires on the PCM harness or bent pins .....
