Standard MOSFET box mod

[Deft-One]

I for the life of me can't get this thing to fire. Its getting power to the 510 but won't fire any of my atomizers and as you can see its getting 4v to 510 when switch is activated. Please please help!!

Check the bottom firing pin on the atomizer. It could be pushed in too far or if it has an adjustment screw need to be brought out.
