Did you get a chance to check the fuse to the electric pump to make sure it is being energized? From what I have read, the IC pump is the most common reason for intermittent supercharger failure. All of the "Stealerships" have their Crossfire trained "expert". Most are parts changers I have determined. If you replaced the IC pump, it is possible that you got a faulty one, new in the box. Good luck and let us know how it turns out.
