Okay everyone, need some help here. I got my 2014 Bennche Bighorn 700 from my father inlaw. He has had it since new and as far as I know never had any problems with it until recently. It began with it being hard to start and having to give it some throttle for it to start up. Then it wouldn't stay running once it did start. If you go to start it, it will fire right off and only run for a split second and then die. If you give it some throttle it will start and stay running as long as your foot is on the pedal. While it's running its pretty rough and backfires. Here is a list of everything I've done so far. Initially I checked compression and it was low. I changed the cylinder, piston and rings. Took the head apart cleaned and laped the valves. Checked timing a few times. Adjusted the valves. New spark plug. Checked the air filter, it was fine. New battery. Changed the fuel pump because of a broken fitting. Changed the fuel filter, lines and fuel injector. Dumped the old fuel and put new in. Changed the air idle control, TPS, MAP sensor, Voltage Regulator, ECU and harness. I was getting codes 31, 107, 113 and 122 on the display. Once I changed the ECU no more codes have been displayed but still have the same issues. All fuses look good and as far as I can tell Grounds are good unless there are some I can't find. I'm at a loss here. Not really sure where to go. Compression was better after everything I did but I don't remember the numbers. I'll have to check it again if someone thinks that could be the issue. Any help would be greatly appreciated!

Can't find a starter for it at all. I have bought 3 and all of them were wrong. Please help me.. thank you Cindy k

I got a 2014 bennche bighorn 700 efi it gets fire it’s getting gas but just won’t start up and half way backfires through the air box what would cause that problem I need all help I can get please and thanks

I have a Bennche 700 EFI Bighorn. I’ve recently been unable to get it to start. After a little troubleshooting I realized my fuel pump was not pumping fuel. This weekend I emptied the gas and replaced it with new. I replaced the fuel pump, fuel filter and fuel injector. I also replaced the battery, spark plug and made sure all my fuses and relays were good. I have confirmed that the float on the fuel pump is not obstructed. The UTV is about 12 years old and has less than 100 hours on it. It has not run in over a year. Not sure whats going on?!? After doing a little reading I'm leaning towards it being an issue with the ECU or perhaps a faulty wire in the wiring harness. Anyone have any ideas on where to start looking or what I could be dealing with? Any help is appreciated, thanks in advance!

I have a Bighorn 500 that I use around the yard to move small trailers and trash. Tried to crank yesterday, no electrical power. Changed battery, checked fuses, turned key, nothing. No lights, no horn or anything electrical. Any ideas?

My side by side will not even turn over. I don't think it's the battery since the lights and signal lights still work. When you turn the key there is no sound at all. I bought it a year and half ago.
