2011 ranger 800xp, 2200 miles. Ran perfect until yesterday, Backfired twice, wont start. Pulled fuel line at connection on top on engine, lots of pressure, pulled one spark plug looks clean but could not get spark, when grounded to head. When I try to start it turns over fine and after a second or two I hear a clicking sound doing something for a second or two. Any ideas where to start troubleshooting. Has fuel. Used every weekend.
