Kinda vague description of the problem, but I'll take a shot at it. Bad connection, dead ignition module or coil, computer problems.

    OK, do you have a service manual? These EFI systems are difficult to
    diagnose without being able to pull the trouble codes from the
    computer. The service manual (not owner's manual) will walk you thru the
    test procedure. If you don't have one, my best guess right now is
    ignition module or cam sensor or crank sensor Again hard to diagnose
    without a service manual. Unfortunately, the only manual I have at home
    is for a 2000 SuperGlide. I believe your EFI system is slightly
    different. Try and borrow an ignition module, cam sensor and crank
    sensor, but make sure it's the right year and part number. Let me know
    what happens. I'm on here every few days and I'll get back to ya.

Harley davidson codes


Hi Anonymous, on twin cams make sure both spark plugs are in heads and use a grounded third plug to check for spark or hold spark plug cable close to spark plug in head. If still not getting spark the usual suspects are:
1. Fouled spark plugs.
2. Battery voltage below 8.7 volts, loose or broken battery cables especially ground cable to frame.
3. Loose connection at ignition coil or plug between ignition sensor and module.
4. Spark plug cables in bad condition, shorting / leaking, spark plug cable connections loose.
5. Faulty ignition coil or ignition / electronic module
6. Failed CKP, CMP, MAP or BAS sensor.
7. Faulty ignition switch.

Just put a big bore kit on my 03 efi softail std , no problem with it easy fit , go to start it and no spark , do i need to reset ecm for some strange reason , didnt touch any thing electrical exept t


Check to see if the injectors have a pulse, if for some reason the connections are loose or the injector wires were put on in reverse, the ECM cuts the spark from the coils.
