I have a 99 sporty , evo engine. I've striped her down all the way. Rebuilt the upper end. Took wireing off to simply the wire harness. I don't an can't get fire. New batt plugs plug wires an coil. I can't figure out how to wire coil. Single fire can someone help

 

What brand ignition?

 

Well originally it was a dual fire ignition system.. If you didn't change the ignition module to accept a single fire coil, it'll never start..
