I like super condensed .... Just so that I understand, when you refer to open and closed loop, are you equating that to a functioning FV and a non functioning one ?
After monkeying with all of the harnesses and connections, I do in fact hear the FV buzzing (I do not believe this was the case during my initial fuel pressure testing). I unplugged it and tested the voltage to it and it was steady at just under 12v.
At this point, I am reconnecting the 02 sensor connection in the engine bay, because (as I understand you?) the ECU needs feedback from the sensor (at idle and below 35% throttle) to properly enrich the system ? Of course, this would be with a running motor correct ?
So far, I have done the aforementioned tests with the FP relay socket jumped at terminals 30 and 87a. As such, when I pulled the FV valve connector, I measured the voltage as a steady reading that was just under 12v. Is this normal ? Should it be at a lesser duty cycle even with a non running motor ?
Next step/test ? Thank You
Bill
