StoneyG, Flybob has the identification to your problem (or at least, this is what happened with mine)
What Flybob has described above is what solved my issue as the flow control safety valve in the pigtail is what was activating with my road side tank. I now solve it a little quicker:
- first extinguish all sources of spark/flame
- wear gloves / eye protection
- close off the tank valve
- loosen off the pigtail connection (large green knob in my case)
- open tank valve (no propane should flow because of the tanks own built-in safety valve)
- while tank is open, slowly screw in large green knob until you hear a quick spurt of propane (PFFFST)
- stop immediately screwing in green knob
- close tank valve
- loosen green knob 1/4 turn
- open tank valve SLOWLY about 1/2 turn
- tighten green knob slowly until PFFFST is heard again, then completely tighten green valve
- slowly open tank valve another 1/2 turn, then open fully all the way
It's at this point I go inside to my farthest propane appliance from the tank (stove) and light a burner to test full flow of propane. *Usually* this process will work and I'm off and cooking with gas. I will only run off that tank until it's low, then manually switch the auto-switchover valve to the curbside tank.
Just a solution that works for me. Please be sure to extinguish all sources of ignition before trying this. Although there is only a very small PFFFST of propane, there is still a chance....
