Thanks Neil for this additional info.   This means that the injector switching is done on the negative side and nothing will happen to the injectors if the constant B+ is missing.     
Yes, the good injector did spray each and every time I moved the rotor.     I even switched the plug of that injector with the one right next to it.  Only the same injector sprayed, thus confirming that the other one could not.      I might even switch that 1 good injector over to the other bank and see if those plugs make it work.   If each plug fires the good injector, this will tell me that the r/h injectors are faulty too and that the ECU and/or wiring is doing its job.     Steve
