Aspire Nautilius AIO WONT FIRE

[ciggrettesarebad]

Hello am new to this i bought my aspire aio 2 months ago and i was really enjoying it instead of cigarettes and i stopped smoking cigarettes since i bought it but two days ago i dropped it and after that it was working well, but after i changed the coil and put a new liquid it stopped firing, i changed the coil for a new one again it started working but it stopped working 1 day after that randomly, i tried replacing the coil with a 3rd new one and it still doesnt work and i even replaced the upper part and try a new one with a new cartage still doesn't work, offcorse i charged my device and it lights up purple normally but i still got no idea why it doesnt fire or heat up, i returned to smoke again those two days because i have no device to satisfy my nicotine needs, can someone please help me asap? i have a surgery in two weeks that my doctor told me to stop smoking before the surgery.
