I have an 03 Road King EFI with an HD Race tuner, 95ci big twin, Rhinehart exhaust, Hi flo air and since I have returned from Sturgis my fuel lite has remained on even with a full tank and yesterday I got an engine lite on way into work. The bike seemed to run fine, no coughing, sputtering or stalling. I plugged computer into it and was rewarded with the codes for "No combustion fwd cylinder" and "primary ignition coil intermittant secondary ok"! I changed coil last yr, dont remember if it was HD or aftermarket. Race tuner was installed to replace failing Power Commander by HD last yr and seems to be running fine. Suspect ECM, coil or temp sensor or ? I am in serious need of technical help on this and of a starting point that wont have me chasing my azz? Thanks for any and all ideas,

 

Just to add to this, this is my brother's bike, and he rides this in all weather, year-round. My thoughts immediately go to a bad ECM, but I am hoping someone out there will know more or have experienced a similar problem.....

Help us out...please....

 

anyone?
