Just bought a 2014 Honda Rancher 420 4x4 foot shift for $1400, shows close to 800 miles. The previous owner told me that it needed an injector, said it quit running so he took it to the dealer which did series of test like compression and other things and they told him it needed an injector. He broke the piece that the sits on top of the injector that the fuel line connects to, but did show me that the pump is pumping fuel to it. What is the best way to confirm that the injector is the problem? It is $60, so I don't just want to throw one at it blindly.
