    AFAIK, you take the plugs out and stick the gauge into the cylinder and with the throttle at wide open, crank.

    just a matter of finding the right size fitting for the spark plug holes.
    Just take out all the spark plugs and I unplug the injectors but its not nessesary, I just think that the fuel will make a better seal and throw me off, anyways just screw it into the hole and try to start the engine, let it turn over about 4-6 times, till you get a good reading. then do the same for all.

    thats what i was gonna do bigdaddy...thanks man. wasnt sure if i had to undo injectors (if you hold throttle at wot it will keep injectors from firing as well)

    I think you hold the throttle at WOT because you don't want any restriction to the cylinders.

    Holding the throttle wide open prevents the ski from starting.

    That's the part I don't get. Some people run with all the plugs in and some run with them out. If they are out, how will it start?

    With the throttle open the ECU will not spark or fire the injectors.
