Protank not firing

[Sa Da Tay]

I've gone through only one fill of this new Protank, worked flawlessly, just refilled and now it's not working on my sigelei Zmax. My other Protank and stardusts are working fine. Any tips?

Is the coil in tight ? try on a different battery/mod if that works your other battery connector needs to be lifted up just a bit not a lot.
Try a new coil if you have one, and if all fail I have no idea
