Propane won't flow? Maybe this....
..is your problem. Had a propane problem where the OPD valve would not open. Got a tip from youtube I thought I'd pass along. Usually when I open the valve *very slowly* it will click open, but...

excess flow is controlled by a little ball that moves to limit flow in case of a hose break.
The OPD has a spring loaded valve that needs to be depressed by the POL or ACME to allow flow. A melt-able piece in the ACME melts during a fire and causes the spring to totally shut the valve, not limit it as does the excess flow.
Container pressure (and spring) keeps the valve closed with nothing depressing it, opening the OPD valve with nothing connected pressurizes the small space between the main valve and this spring loaded mating surface for the POL/ACME. Shutting the main valve leave pressure on the spring loaded mating surface and may require extra force to open when attaching an ACME/POL.
