I got an 800 polaris efi fourwheeler I've checked the fire on the wires going to the coil they got good fire but the coil it only firing on 1 side I've traced wires the injectors are working the stator has fire on all 3 wires but ito still only got fire on one side we've replaced the coil but its still only got fire on one side

 

You have a service manual or just working with a meter on this? Plus what year model?
