    Suddenly my bike wouldn't start and the "FI" warning light is constantly on, does not flash. The bike powers up like normal but won't even try to start.
    I checked all of the fittings, connectors, ground and anything I could get to and everything is in tact.
    ....some recent history.... I laid it down in a deep mud puddle and had water in my airbox. After a 150 mile ride home, I cleaned the airbox, filter, changed the oil and filters and somehow the throttle body was clean.
    Any input would be appreciated, thanks. I'm trying not to get bent over at the dealership.

    Mass air flow sensor would be my first guess. I know nothing of KTMs but EFI bikes have them in one form or another. You are going to need something to read the error codes to trouble shoot this. You may well be better off taking the bike to the dealer.

    Disconnect the battery and try it again. You never know. Most EFI bikes use MAP rather than MAF sensors.

I laid it down in a deep mud puddle and had water in my airbox. during my 150 mile ride home it ran fine, I cleaned the airbox, filter, changed the oil and filters and somehow the throttle body was clean. I was just putting around yesterday and then it wouldn't start back up.

    I don't think it's anything EFI then. Side stand switch? Starter button (ignition button to you)? Neutral switch? Clutch level switch? At this point you don't know if it will start, you do know it won't crank. Will it bump start? Try that, it won't fix anything or solve your problem but it may prove if it will start or not.

    Guess we all have similar questions. You turn on the key and the dash lights -hear a fuel pump run for a few seconds? Then push the start button- engine cranking or nothing? Get us clear on the basics and someone can help you figure it out.

    Its a good bet your battery is dead so get it tested.

    If its not the battery you can try putting a screwdriver across the starter solaniod and see if it cranks. If it does you have a short between the starter and auxiliary starter relays....In my case a broken wire under the battery box.....the bike should run by push starting if this is the problem (if you don't want to short the solinoid) but shorting is way less tiring :knary

    Other than this it is likely to be one of the cutout sensors mentioned a few post back......but my money is on the battery

    If the battery hasn't got the juice to engage the starter relay you can try removing the headlight fuse to give it a bit more to get it cranking....worked for me once out in the boonies. Good luck.

    try the easy things first
    check all connections,
    check fuses, sometimes fuse looks ok but its blown, good to check with multimeter.
    charge battery
    put in neutral, clutch in, side stand up.
    just to eliminate some switch issues.

    i had lose connector on diode on my 640 and it wouldn't start.
    the diode was in the headlight housing. check connections there and maybe check diode with multimeter too.

    there is also a rollover sensor i saw in 1 of the diagrams for 2010 690
    check all switches(clutch,sidestand etc) with multimeter
