I have a 2003 fat boy fuel injected, after doing my push rods and cam chain tensioners, timed perfect and running well , left me on the side of the road a week later. After this I have put a new fuel pump and injectors cleaned the fuel rail and have great fuel pressure, that being said brand new plugs. Fired her up and ran rough , was gonna take a test ride wouldn’t start after that, noticed that my plugs are fowling. That’s as far as I have got ,would there be codes that need to be cleared ??? send help I need to get back in the road , thanx y’all, new here
