    Fuel left on

    I came home today after being gone for a couple of days....only to find that someone has been playing with the Jet Ski in the garage....someone decided to turn on the fuel.....

    So the garage smelled like a fuel tank when I got home...and now the Ski won't fire up....

    What now?

    Is there gasoline inside the hull?

    If you have fuel or heavy fumes in the hull, clean it up and ventilate thoroughly before trying to start it. Any spark with gasoline fumes present could cause an explosion and/or fire in the hull, so be careful.

    Is the engine flooded with liquid gasoline?

    Take the spark plugs out, ground the plug wires, then crank it over. If fuel sprays out, then you have liquid fuel inside the engine (not good).

    Do NOT try to start it any more.

    Find out what has happened.

    Disconnect the battery VERY CAREFULLY. No sparks.

    Use flashlights, not 110 volt trouble lights. No sparks.

    Loosen the gas cap. Sounds like the check valve in the vent line might be jammed up. It runs up under the bar pad on most skis.

    Take the seat off, and the storage bucket.

    Use your eyes and fingers to figure out where the fuel has gotten, then clean it up. Be sure to put the gas soaked rags in a METAL container, in case they catch fire.

    Get the fuel cleaned up, then wipe it down with cleaner to remove the fuel residue. Ventilate the hull and surrounding area thoroughly.

    The fuel tank may have developed excess pressure during the day, and with the fuel valve open, the fuel forced its way into places it should not have gone. Open the gas cap to relieve any remaining pressure.

    Perhaps the vent system for the fuel tank has a problem (clogged or stuck vent valve), and the vent is releasing liquid fuel (which it should not normally do).

    It's a 2000 Kawasaki 900 STX...I just loosened the gas cap and it made a big "Hissing" sound....there was pressure on it.
