Thanks MPDano for the advice. I have actually taken all of those steps and everything checks out ok. The nine filters are free of junk...never were really clogged to begin with, but I cleaned them all. I also tested the injectors and got a fairly nice spray out of all of them with carb cleaner and compressed air.

I hooked the AAV up to power and turned on a heat gun and carefully blew around the valve and got to watch as it closed...so I'm assuming that was a good test...and then it opened back up as it cooled.

The big mystery is why fuel would stop squirting out of the injector the farther i push down on the sensor plate (correct term)

It is working like a pump...lol...I can push down and fuel sprays out injector and then stops...so I let the sensor plate come back up and push down again...fuel sprays out the injector and then stops.

I really think this is my problem if I could figure out why it's doing it.
