With the key still at #2 after time and that geyser is released, then there is hardly any pressure. SO pump does not run continuous in #2, only initial run/up pressure??

Back to my test, I build pressure with key in #2, wait and after 3 min or so there is NO gas on the rag and the pressure at the schrader valve is a tiny "poof" sound and NO gas released.

SO I am leaking pressure somewhere else??
(and its dry at the fuel rail connection at back)

THANKS!

That is correct, fuel pump runs initially just to power up the pressure but turns off if the engine does not start. Once the DME determines that the engine has started or is cranking, the DME will command the fuel pump on.

Turn off the ignition switch, wait and turn it to position number 2. Wait, turn it off and turn it back on to position no 2. Turn off the ignition switch and check the Schraeder valve again. I bet you will have a geyser of fuel when you depress the valve.
