Okay, if you have the basic coolingmist kit you should have a red wire with an inline fuse going to the pump for power. Right? Check that fuse. Mine did the same shit and it was a blown fuse. I have mine hooked up to the cigarette lighter (Terrible idea) and when the cops were hitting me (Radar detector beserk) I think it busted the fuse
Either way don't fret, just check to see if that fuse is blown. Either the power/ground got disconnected or that fuse is blown.
This is exactly why I advocate that people should always have a scangauge. You can see exactly when your meth stops working...because depending on the tune you might not see a crazy difference in AFRs. If only the numbnuts in the DSP section would understand
