so, I am trying to sort things out here with my random no start issue and have a question to all who may know: Does the shut-off valve open and stay open right when key position 2 is reached? or Does it click open and close real quick then open again at crank?

scenario 2 is what seems to be happening for me, when it starts. when it does not start i can see the valve is not open, because the bottom line to lift pump pulls tons of tiny bubbles out of the fuel there during crank, as like the clear line pinch test resulted in. when i unplug the connector and watch voltage, it spikes, then drops down to .71 volts.
anyone know?

Thanks everyone!
Ian
