    Starting problem on vx-110

    My 2007 VX-110 refuses to start.

    What I Know
    I have the latest YDS software and cable and had a bad intake temp/pressure sensor. After replacing the ski now fires briefly and then quits. If I leave it for a period of time (an hour or two) it will fire again briefly (less than 2 seconds) and then quit. Subsequent attempts to immediately start produces no fire at all.

    YDS diagnostic says everything is fine.

    I have fuel to the injectors (don't know what the pressure is though).

    I have spark top the plugs (it fires briefly... so there must be spark).

    The engine has compression (haven't measured all cylinders yet).

    Voltage is good.

    ECU is good. Cuz YDS says it is.

    Injectors can be heard clicking if I do the stationary injector test.


    What am i missing??????

    TIA.

    Try starting it with full throttle.
    I've come a cross this a few times.
    Once running it will start & stop just fine.

    Maybe the kill switch is going bad?

    Also if the TPS senses any position other than closed, it will not start.
