Hello, We are kinda new to this forum and need some advice on what to try. We got a 1998 1/2 Dodge 24V that we completly rebuild the motor in. We added 270 hp injectors, 120 hp Edge box, Put the motor back in and it will crank with a starter button and run but will not with key and the instrument cluster does not work. The security light come on then goes off. We took the Body control module to the Dealer and had it flashed or reprogrammed. Then we took the truck to the dealer and it said that they truck wasnt communicating with their diagnostics. Truck runs,drives, AC radio lights all work fine. Pretty much the only thing that doenst work is the key and the gauges. We even tried another cluster and it did the same thing. Any ideas? Any help is greatly appreciated!
