What atty are you using? I have been trying to troubleshoot this for you and I keep reading where the center pin needed adjusting because it was not firing. I have taken a small screw driver and just turned the pin on the bottom of the atomizer to adjust the contact. See if that helps. Sorry, at this time you just get a insomniac that doesn't know much but wants to help. Others will come along I'm sure and help you more.
