    I have a 96 seadoo sportster and I can't get any fuel to the carbs and does it have a fuel pump in the tank and if it does I checked the wires and it has no power going to it

    Those wires are for the fuel level sending unit there's no power to them, your Mag (front side) carb has the fuel pump built into it.

    so there is no fuel pump and the carb pumps it?

    The mag side has the fuel pump attached to it, it's a crankcase pulse operated pump with check valves and fuels both carbs.

    All DESS security equipped MPEM modules can have the security disabled with the press of a button from a service provider using the correct Buds or CandooPro software.

    An old style clip lanyard switch that closes the circuit can be used to turn the module on and off at that point or any DESS key with a good magnet will operate things with the existing DESS post so long as the magnetic reed switch remains working in it.

    There is a downside to shutting off the security in the module, there are credible reports that some MPEM's have become unresponsive and stopped working although it's never happened to me and I've turned off several over the years for owners that simply hated the security and wanted it gone.

    This what the programming screen looks like to shut the DESS security off:

    would it be a good idea to block off the oil pump and just mix the gas?

    As seasons come and go, I find oil pumps manage to never forget to add oil at the right time and some people's brother in law borrowing the boat/ski for the day manage to get that part wrong on occasion.

    Besides, you have a rotary valve case that requires oil constantly from the same oil tank that supplies the injection pump so why bother?

    one more question are there any reed valves?

  10. #10
    does the rotary valve take the place of the reed valves?
