I have a 2007 Artic Cat 700 EFI (new to me) I jumped with wire to get code _ec00 so that seems ok? I think I’ve narrowed it down to the ECU area? When I wiggle the ecu or press the support plastic under it while running it will cut the engine and display again. Hoping it’s not the ecu itself and just something loose? I’ve blown things out real good with air hose, checked for obvious connection issues, no corrosion? Charged the battery too. Any suggestions?
