I just measured the injector connectors(at the opened harness) with the car running and plugged into the injectors. Between 13.2-14.2V on the left pin. The right pin has pretty solid 14.2V
I have a innova 3320 multimeter set at the red 1 oclock position and the wires plugged into the correct slots for all the tests. Yes it "auto ranges" when not touching the red prong to anything.
It stopped auto ranging on the right pin at 0.0V with the key off. (It never stopped auto ranging on the left pin)
Here are the newest codes again since I deleted that last post:
