Does it hit at all? I had a problem with mine where it wouldn't fire at all. I had to pry the connection up with a small screwdriver. But you may have a fried coil. Replacements are cheap. Personally I hate my T3. I've found that I get better flavor with a carto tank. Just to be sure I filled up my T3 with juice today, and the flavor is non existent compared to my smoketech carto tank. Not sure if there is something wrong with mine too, but I don't even want to use it anymore. Sucks because I have an unused replacement head for it still in the package.
