I have a 97 Polaris 425 magnum. The spark plug wire took a crap so I had to replace the coil and the wire since it is all one piece. Now it wont start. I tried putting a new plug in no help, made sure the battery was fully charge no help, I did check to make sure that i am getting spark but it still wont start. Ocassionally it will back fire while tryin to start it. I have also tried useing starting fluid but that didnt do it either. Any help or suggestions would be appriciated
