Yes, pumps were running. I corrected the issue with the pumps running all the time, the yellow relay socket was loose. After snugging the pins in the rubber socket, the metering plate switch now works correctly.
I did verify I have no voltage at the frequency valve, so I'm going to chase that rabbit up stream to determine where the issue may be. Does anyone have a pinout of the diagnostic connector in the engine compartment?
I do get 12V with the key on at the top pin, but nothing anywhere else.
