I recently just fixed an issue where the EFI fuse was blowing every time you would turn the key. It ended up being a short in the key switch so I replaced the switch. Now I have power to everything and the motor will turn over, but it will not crank. I found that im not getting fuel and spark. I haven't done a lot of investigation on the fuel, but on the spark side, I am getting power to the coil, and the coil and spark plug wire are good according to the remittances in the service manual. Im not sure what steps to take next. I have checked and double checked all relays and fuses. According to the owner of the Polaris (a friend of mine) this was not an issue before the refi fuse started blowing.
