Did you "prime" the wick and coil first? That's really important. Priming is a matter of making sure the coil and wick material are good and wet with
juice before your first puff. Also, with a 2.2ohm coil, you don't need much power to run it and maybe your wattage/voltage is to high?
I always recommend that you start at a very low wattage/voltage on a coil and bump it up to what it should be during the "break in" period.
Be careful about how much you cut from that silicone piece, it's there to not only keep everything in place, but to prevent flooding from to much
juice.
