    SHO 88hrs Can't start the engine

    Hi everybody,
    I'm in front of a problem, my sky doesn't wanna start 09' FX SHO
    I crank as usually, and then it doesn't start.
    I've been using it for more that 80 hours without any minor problem, never have anything. I went for a ride on saturday, everything was ok, i had to tow a friend's ski though. And then, yesterday (sunday), 8 o'clock, the ski doesn't want to start?
    Could it be something related to the ECU ?

    Let me know if there is anywhere I can start checking.

    Just poking questions to get some more info.

    1. If you crank for a few seconds do you hear the fuel pump run (buzz and or bildge pump run?
    2. Do the gauges seem to work or nothing at all?
    3. Can you check for spark?
    4. Checked fuses?

    Hi there buddy,

    No need to panic, I had the same problem Three times on my 09 FZS. In my case I started by checking fuel pressure and didn't have any so the dealer replaced the fuel pump then the problem came back and it ended up being a faulty wiring hardness. However in your case with this many hours I bet anything it is the BILGE pump fuse. Now you may say WTF!, YAMAHA on an effort to ensure proper bilge pump functionality decided to have the Fuel pump, Injectors and Bilge pump on the same fuse, I know it doesn't make any sense but I guaranty you there is your problem. I had this happened to me two months ago. Take care, Julio...

    Be absolutely sure the ski is unlocked using the key fob.

    Yes, me too. It will crank all day long but will not start if it's in "locked" mode.

    Hi,
    thank you for all your feedback. I will check for the fuse tomorrow. the ski is not locked for sure, triple check :P
    Got ignition and crank so it's logical must be related to the fuel supply, Will try the blidge pump test tomorrow.

    Best regards

    My SHO did that after 5 hours. The problem was that the throttle cable wasn't adjusted correctly. It was a little off the stop and that tells the ECU to crank and not fire.
