    99 Genesis will not stop running.

    I'm working on a 99 Genesis (fuel injected) that will not stop with the stop/start switch or the lanyard. The switches test out OK. Is it likely that the stop/start regulator has gone bad? Is there a test I can do to it to see if it's good?

    Sounds like you're stator or CDI is not grounding out when you press the stop button.

    How are you stopping the engine if the switch and lanyard are not working?

    4010263 - 1999 Genesis Ficht Start/Stop cut-off (inside electrical box)

    The 1999 Genesis Ficht system is a little different that the later model years, and I do not have a 1999 schematic to work from.

    I am referencing the 2001 Genesis i schematic. For 2001, the safety lanyard and Start/Stop switch are different circuits, with the lanyard directly grounding the Black/Yellow wire.

    Having said that, the Black/Yellow wire is the engine kill signal to the EMM. When it is grounded, the EMM should shut down the engine.

    Check that removing the lanyard is indeed grounding the Black/Yellow terminal in the electrical box (and pin 8 on the 40 pin EMM connector).

    I expect that the 1999 Genesis i Start/Stop module is also supposed to ground the Black/Yellow wire, when the engine is running and the button is pressed. The Start/Stop module typically determines whether the engine is running based on the RPM signal from the Yellow wire, and gets the Start/Stop button press signal via the solenoid negative wire (Black/White).

    Hope this info helps you diagnose the problem.

    Thanks for the reply. I've been too busy with other jobs. Removing the lanyard does ground the black/yellow wire. Does this mean that the EMM is bad? Is there a way to test the start/stop module by itself?

    Where did you test the Black/Yellow wire lanyard grounding?
    At the EMM connector?

    If grounding the Black/Yellow wire right at the EMM does not kill the engine, then the Start/Stop module is not the problem.

    I don't know of a away to test the Start/Stop module outside the hull, other than rigging up some sort of test bed, which would take a bit of doing.

    How are you stopping the engine right now?

    I checked it at the EMM connector inside the electrical box..

    I disconnected the injectors.

    Check the Black/Yellow right at the EMM. Loosen the retaining screw, and check right at the Black/Yellow EMM pin 8 in the 40-pin connector for continuity to ground when the lanyard is pulled off.

    While you have it apart, look for any signs of corrosion around any of the 40 pins on the EMM.
