I have replaced the cooling pump with a Johnson and replace a fuse #13 once still good and am still having intermittent problems with the super charger,does anyone have any other suggestion before I pull the pump and check it . It does not seam as bad as when I first replaced the stock pump just when I am repeatedly trying to make it work.My SRT6 roadster has 17000 miles and still has a lot of pep but I miss the acceleration of the supercharge all the time .l only thing left to change is the ambient temperature sensor and am still having problem, Just wondering why the check engine light has never come on.anyone have any clues.
