Searching google for that exact text in quotes (what the scanner shows) yields basically no results. What does it refer to?
For some context that lead to this question, I'm not getting my injectors to fire, but I cam getting good spark, and this "Valid Reference Pulse" shows "No", most of the time; the injectors DO fire, but rarely and randomly, and when they do, "Valid Reference Pulse" switches to "Yes" (but only for that second or so).
My distributor is new, and I've also replaced the cam sensor that it came with, but this hasn't changed the behavior. Also, my
SECURITY light is off. The scanner shows no codes on the Engine, or OBDII, just a code about the ABS.
