2003 Road King Classic was running fine. Had someone stop over and let him take it for a spin. Stalled once and had to get it fired but easy no problem. Followed the guy back home 1/2 a mile he jumped on it once and going back and then in the garage turning it off. Next day tried to start it up and it would not. Replaced the battery and still will not start ever since that day. Everything works perfectly - Lights, hear the fuel pump kick on, signal, brakes, switches appear fine and I changed the gas to highest just in case and nothing. I checked spark by pulling a plug and starting while on the cyl. and no spark. Put a new coil in it and nothing. Cranks great and all is appearing to be fine but no fire/start? Had somebody come over to check the codes jumping with a female end and he said taking out the battery killed the memory and no codes showed up. I am completely lost on this one. What to do What to check??????????
