Let me start by saying I've owned Harleys for twenty years and do all my own work, so don't let the computer expertise on my profile detour you from taking my advice. There are several things that can cause a no start, you'll need to narrow it down to either a fuel problem or a fire problem. Start by checking the spark. Take a plug out, ground it to the head, and crank the engine. If there's is no spark then you need to start tracing it back. Check the coil, ignition module, and voltage regulator connections and wires. Most of the time when you lose fire it's a loose or broken wire/connector, or the coil or ignition module has failed. The regulator can cause a loss of spark, but generally only causes the battery to go dead. Rare, but occasionally the magneto will go out. If you have a good spark, then check for fuel. Turn off the petcock and take the fuel line loose at the carb or injection end, then turn the petcock back on and see if you have fuel getting to the carb/injection system. If not, then you have a faulty petcock, or a plugged screen in the petcock. If you are getting fuel, then, if carbureted, take the carb off, clean it, and check the jets and other internal workings. If this is an injected model, I'm afraid you'll have to take it to a shop that has the diagnostic tools to read and calibrate the injection system. Wow, this is starting to get long winded. Try these and let me know, I have a wealth of knowledge available to me from guys I ride with.

HD Fatboy Starting problems


It sounds like you have a short in your start button wires, this could be caused by having custom bars with internal wiring. The wires chafe, touch, and it bypass's the button altogether. I would check continuity at the connector on the 2 wires of your start button and see if it changes whether the switch is depressed or not. If you have continuity both ways, you have a short. You should not have continuity unless you depress the button. If all looks well, re-post.
