    Well, lets work through the no-spark diagnostics in the service manual.
    Starts on page 315 in the 2002 service manual.

    Do you have access to another EMM?
    If you do, swapping the 8 and 12 pin connectors to the alternate EMM would be a useful check.

    The MFI will go to sleep after five minutes of no activity. When it wakes up, the speedometer dial cycles full sweep, and all segments of the LCD light up.

    Does the MFI 'wake up' from sleep when you start cranking the engine after it has been sitting for more than five minutes?

    Once the display is awake, does it show RPM while you are cranking?

    You can change the MFI display mode to put the RPM in the main display. What RPM do you see while cranking?

    Unplug TPS at rear of throttle body - does it start, or spark??

    Check the CPS coil ohms (Crank Position Sensor). Should be under 200 ohms.

    Check the ignition coil ohms, and check the coil grounding to the engine.

    Unplug the 12-pin EMM connector, and check the stator coil ohms. Also check the stator coil AC voltages while cranking the engine. Page 306 (8.2).

    Lanyard & Stop switch - Black/Yellow wire (12 volts?)
    Find the Black/Yellow wires that connect to the LR-503 module.
    What voltage is on Black/Yellow with the lanyard removed while cranking?
    What voltage with the lanyard in place while cranking?

    After unpluging the TPS I got "SPARK" and it started, pluged TPS back up and still have spark and it still starts and runs. Doesn't run very well, think the plugs are fouled, I'm charging the battery back up right now. What does unpluging the TPS have to do with ign. coil voltage???

    Now you are getting somewhere

    The EMM will not allow the engine to start if the TPS signal is out of range.

    TPS can go bad over time, as they are exposed to engine vibration and moisture.

    I suggest you buy a new TPS. When you order a new TPS, you will get the latest version.

    Sometimes the individual connections inside the TPS electrical connector get dirty, or do not connect solidly.

    Have a look at each connection pin and socket, and clean them up if they are contaminated.

    On my own Ficht machines, I used thin pliers to gently squeeze each socket a little tighter.

    I also replaced the TPS on each machine with a new one, and put the old TPS aside as a spare. The newer TPS is a better design, with a sealed 'overmolded' body.

    Photos show older TPS design, and newer TPS design.

    More TPS photos (pig-tail style).

    Note the orientation of the tension spring with the TPS installed. It must be correct, so it does not bind as the throttle shaft turns.

    Correct torque for the TPS bolts is only 8 ft-lbs. Do not over torque.
