I have a 2010 Rhino 700 that has set for a year or so. Now when I try to start it, it will start right up and the die a few second later. Pressing the gas peddle doesn't help. I changed the spark plug and cleaned the air filter. I siphoned all the gas out of the fuel tank that I could and put fresh back in. After that I started it several times and it would do the same thing...die in a few seconds. I can hear the fuel injector kick in when I turn the key to start. Any suggestions would be appreciated.
