I have a 2015 Diesel Crew with the Kohler engine. It suddenly quit starting. I checked what I could with no success in getting started. I took it to a local small engine mechanic who works on a lot of small diesel tractors. He said he checked the fuel pump, fuel injectors, and glow plugs but had no success in getting it started. He said that in his opinion, that left only the ECU and l would have to go to the Polaris dealer. Going to the nearest Polaris dealer (30-40 miles) gives me cold chills due to the dealer reputation. Does anyone have any ideas? Is there anyone to send the ECU to for diagnostics and repair? Based on what has been checked, does it make sense that the problem is the ECU? Any help or direction would be appreciated.
