    Welcome.

    The challenge is that if you cannot do the work yourself it can get expensive quickly to pay someone else, if you can even find someone that knows Polaris Ficht. Most PWC techs will not work on any Polaris watercraft and almost certainly not the Ficht fuel injected engine.

    Are you willing to take the project on, learn how your machine works, and dive into the diagnostics?

    The folks on this forum will help as much as they can.

    I am mostly out of the Polaris repair game. When I was helping others more directly, there was almost no-one else in the Toronto GTA region that would work on Polaris Ficht direct fuel injection engines.

    This link should prove to be quite useful

    first thing i would do is check spark....my guess is the emm is crapped out...far more common then fuel pump complete failure.

    My first guesses are

    failed emm
    failed stator

    I do have a couple of contacts that are (or may be) willing to assist with Polaris Ficht diagnostics and repair, but they are not local to Toronto. One is near London and another is near the Big Rideau Lake region.

    Let us know how you want to proceed.

    Read the link that k447 sent you. If your mechanically inclined this is something you can figure out. First is check for spark. If that's good, check for voltage at the white red wire of the diagnostic connector. Should be around 25 vdc while cranking. This is your injector voltage. If neither spark or volts are present do a ohm and voltage test on your stator. If that checks out check the cps for ohms. Should be around 130. If cps and stator test good the the emm is most probly bad. Send it to Lakeside tech for repair.
