If I understand them correctly, a pigtail won't flow if connected to the bottle and the other end unconnected. I believe they need system back pressure to hold an internal valve open? But not 100% sure on that.
The best test would be to put the suspected bad pigtail on the known good side of the regulator with a known full bottle.
Then put the known good pigtail and known full bottle on the side of the regulator that didn't work.
If the suspected bad pigtail flows on the suspected side of the regulator, then probably a regulator problem.
If the good pigtail flows on the suspected bad side of the regulator, then regulator is probably good.
Then I would be quite sure it's a bad pigtail.
On the other hand, they're relatively inexpensive so preventative maintenance might dictate to replace them both. I did just that a couple weeks ago, when I had a pigtail begin to leak at the crimp joint.
