I have a 94 ram van that has no spark! The crank sensor has been replased,coil is good i currently traced the green and orange wire coming from the asd relay and it was grounded when the book says its suppose to get 12v. I have checked the circuits it works with and all were working except the o2 so i snipped it and now getting the voltage i need to the coil but stillllll no spark. Can anyone please help me with this.also disconnected wire harness from computer and got power from the green and orange wire. I have no idea what else could be wrong if im getting voltage to the coil with no spark.
