No start problem
 

Hi everyone new here, I just bought a 2006 boulevard c50, 17,000 miles. turns over no fire. Sometimes it'll start run for a bit then shut down, a fast crack if the throttle chokes it out dies then doesn't restart turns over. I've checked plugs with them out they are firing, when pulled they were soaked with gas. Pulled injectors both are firing. Has new injectors and ecm he replaced due to this current problem. This is probably a electrical issue with 1 of the safety switches but for it to choke out with fast throttle (it'll rev up slow) I'm not sure. Guy I bought it from said crank shaft sensor, but I have no flash codes for anything. I'd really appreciate any insights you guys have as this is my first fuel injection bike and my background is diesel I appreciate it.
