Hooked up an EZ on a '01 Ram and took it for a ride and the "Malfunction Indicator Light" came on, and stayed on, and absolutely no power. Rechecked the connections and the stock engine wiring harness connector into the supplied MAP sensor connector was loose. Tightened this connector up and all kinds of power, but the malfunction indicator light stays on. Any suggestions on what to do next? Should I disconnect a battery and hook back up? Any help would be greatly appreciated.
