I have a 96 XP that the engine will turn over all day long, but I cannot get it to fire. It has fuel and the plugs are new, but it will not seem to pickup spark. I have tried everything I can think of, and I need some help. I checked all the wires and everything is good, is there some sort of self diagnostics I can use with the DESS cord? I get 1 beep when I first hit the start/stop button, and then when I put the DESS cord on the post, it beeps 2 times real quick. and then I can hit the start button and it will turn over but not seem to fire. Thanks for any of your help it will be greatly appreciated!
