heya Ryan - are you using the subtank and which coil
sounds like either coil is not seated properly (needs to be screwed in finger firm) or possibly center pin in mini has gotten pushed down (check pin - do you see any black marks or spots on it?)
if it is reading 9.9 ohms, don't fire it - will be sending way too much power to coil (amps wise)
*correction - not amps wise, voltage wise
