    2004 Polaris Virage has no spark

    You guys seem like Polaris genius' on this board so I hope you can help.... any way here it goes.

    My 2004 Polaris Virage has no spark when cold if I disconnect the battery and reconnect it then take a coil wire off it some times will start.... Once it starts it runs perfect till it cools back off.... Anyone have a similar issue?

    Welcome

    Fuel injected or carburetor?

    Two cylinder engine?

    If you re-connect the battery and leave the ignition coil wires all connected, does it start?

    What spark plugs are in there?

    What is the battery voltage while the engine is cranking when cold?
    Measure with a multi-meter, not the digital dash display.

    Thanks for the basic info!

    Its fuel injected Two cylinder It has NGK resistor plugs not sure of the number... voltage while cranking is high almost around 10-11 volts.

    If I just reconnect the battery and not touch the ignition wires it will not start.

    All I do to get it to start is remove a wire off the coil not a ignition wire and it will start and run on one cylinder. Then while running I plug the other wire in to the coil and it will run all day till the motor sist for a few days again....

    This is one of the strangest problems I have ever come across....

    is high almost around 10-11 volts.
    10.0 volts is too low = weak battery.
    11.0 volts would be strong. Big difference 1 volt makes.

    What exactly are you unplugging?

    Are you disconnecting one of the fuel injector connectors (two pin plug, slides down towards the engine top to unplug)?

    If you are indeed unplugging one of the fuel injectors, then the EMM likely has a weak power section. Unplugging one injector reduces the electrical load on the EMM power supply, and allows the engine to start.

    The EMM can often be repaired.

    As far as voltage goes I tried two different battery's as well as jumping it from a car. I'll double check the voltage anyway. I disconnected one of the power leads to the coil not the fuel injector and not a high voltage lead to a spark plug... A low voltage power wire for the coil... and it will start then while running on one cyclender I plug it back in then the ski will run flawless for the entire day...

    Make sure the spark plugs are NGK PZFR6H. No substitutes are allowed.

    You are unplugging either the Orange/Blue or Orange/Green ignition coil wire - correct?

    And that is enough to get it to start?

    Ohm check the grounding of the ignition coils to the engine block AND to the battery negative. Unplug all the wires from the coils, and confirm zero ohms to the engine and battery negative post.

    BTW, that 'low voltage' coil wire is about 300 volts!

    Its the wire more toward the rear of the ski on the coil I think its orange and black but its been a week since I looked at it. When I made the reference to Low voltage part of the coil I was simple trying to say its not the spark plug wires lol.

    The grounds all look clean but i'll check them out with my fluke...

    So i'm guessing this is something you haven't seen yet... That would make perfect sense because I always seem to be the ground breaker when it comes to problems
