It definitely was the battery! Jumped her, and she started right up. Thanks for the advice!

Hmm good point! I didn't even consider the battery/voltage as an issue, because why would a battery issue throw an EFI fault? I will try this out and report back when I have time! Thanks for the advice

So I have never had any issues with my 500 until today. I went outside to go for a ride, and before I started it up I turned the key to check the gas level. It was low so I gassed her up, and then when I jumped on to start it up the EFI light flashes.

Now, this isn't to say that it is flashing a "code". When I turn the key, the EFI light is NOT on. It only illuminates when I attempt to start the machine. When I press the ignition button it flashes the entire time I have the button pressed, and does not illuminate again.

Again, there is NO CODE being flashed, whatsoever. It simply flashes when attempting to start the machine. Has anyone seen something like this before? Obviously I will call a dealership tomorrow and see what they say, but I'm not sure it'll be much help until I get the ATV over to them (since there is no code being flashed, it isn't going to give them much to go off of).

Any input would be appreciated! Thanks!
