Believe it or not, If you search through here you will also find its very common for the fuel line inside the tank to get a hole in it then unable to pressurize the system. Happened to my bro's bike, 07 UC. The backfire symptom as well as unable to run into higher RPS often times as it progresses it wont even idle, just backfire cough and die. Food for Thought, Good Luck...
ArizonaHarleyRider, I am have a code P1356 with my '07 Street Glide. I have no spark at the rear cylinder. I have replaced the plugs, plug wires, tested the coil, and unplugged the Power Commander, but with no luck yet.
How many miles were on your 07 UC when it got the holes in the in-tank fuel line?
Can the unpressurized fuel system issue cause the ECM Computer not to provide spark?
Thank you for the help.
