HELP, Code 12 showing 700 won't start.

Hi Guys,

Some of you may remember, ever since I got my big 3 installed I have been having issues. First seemed to be the battery, then the regulator and now thought it was the stator. Here is exactly what the 700 was doing before I replaced the stator. Quad would run great with headlights on, turn them off and it would run very rough, poppin and spitting. Ran it that way for a while with headlights on but started noticing on nice easy trail rides the battery would lose charge ultimately requiring jump starts to get it running. I thought, ok time to replace the stator. Well I replaced the stator and while there put on the new regulator. Quad tried to start but would not run. Put old regulator back on without headlights turned on and it tried to run then stopped. Now the motor will turn without issue but will not even try to start and I have a code 12. I checked the stator connections and they are fine. I disconnected the battery over night and still no change. What the hell is going on??? I love the fuel injection but starting to wish I was running old school carb again.

Please help me figure this out so I can ride and enjoy this beast!!
