First i'd look at my wiring... just make sure that it's not cut or frayed anywhere... make sure there is a good connection on EVERYTHING. I had an ignition signal problem and a wire was loose to my aftermarket coil. I got rid of that sum ***** and put the stock one on. make sure all your grounds are there too. Your ignition coil could have gone bad. Oh BTW. C if you're getting spark and write back.
