    Fx Ho no spark

    Hello everyone.

    I have a 05 fxho that is kicking my butt. It only fires once n a while. I have tried every thing I can think of but end up with the same result. Here is all that i have eliminated thus far. coil's , pulser coils, thermoswitches engine and exhaust, ecm,cam position sensor, tilt switch ,kill sitch. I installed a known good part on all but the thermoswitches but they check out by the manual. also the ecm I tried is a fx 140 it is a different part # but the original ho works on the 140.Thanks in advance.

    there are differences between the ecu's. depending on years. things like the individual coils compared to the 2 coils on the fx140. just something to consider.
