Yeah, I know, wrong forum but anyway. One of my bunton 28 kohler efi's shut down today and won't start. It stopped all of a sudden and would not refire. It will turn over so its doesn't seem like a safety switch thing. When you turn the key to on it is supposed to turn on the pump and the orange light comes on, that is NOT happening.I am lucky enough to have three similar units so I swapped some of the usual suspect parts like the key switch, the three relays, checked the two fuses then even swapped to make sure, and I also swapped the little module next to the relays, (I think it is called a delay module). Still no go, any ideas???
