2007 Arctic Cat 700 EFI NO SPARK PLEASE READ

[surbike11]

Thanks in advance for any help or guidance. I was out riding the other day and lost all spark. I have read every thread on every forum that I could find and have not found an answer. I have checked the codes and its 00. I have ohm metered the stator and crank sensor. I have also replaced the coil pack. I have inspected and cleaned all connections. I do not mud the machine, it is mostly used at the hunting lease for working plots. When I installed the new coil I held the plug on the side of the engine and got 2 little sparks when first turning over and then nothing again. When you turn the machine over like this it eventually flashes EFI on the screen. I checked both wires that go to the coil and noticed that both have ground continuity. While turning over the blue and white one cycle from around 1v to almost 12v. The battery has a full charge and I am at a total loss. I took the kill switch apart and all looked well. Oh yea and all fuses are good. Help me please I am getting very frustrated. Thanks

neutral/safety switch ?

[surbike11]

I have not checked that. I honestly figured since it was spinning over that it wouldn't be that. That said I am not even sure where the neutral safety switch is lol

it should be on the backside of motor ... looks like an oil sending type unit, probably 1 wire ... if the safety switch is damaged, its an easy fix, all it does is allow spark when in neutral ... i have seen some bikes that have a light saying they are in neutral and no spark, replace and spark again ... hopefully this is all it is ....

kill switches sometimes get corroded and ground out ... most switches can be taken apart ... maybe try that too ?

Just an update, I have ohm checked everything and pulled all plastics off. I haven't found a smoking gun. I am starting to think that it may be the ecm, any thoughts out there on that being the condition? Thanks for the help please

last thing I had do that was an 04 arctic cat 90, did almost the exact same thing, it was the cdi box. have you checked the rectifier? I doubt that's it but I would check it. also it may sound stupid but smell the cdi or ecm, usually if they are bad they will smell burnt.
