Ok I have a 2014 honda rancher 420 4x4 foot shift. I bought it knowing it wasn't running and the guy said its a bad or stuck open injector. I pulled the injector off and turned the key and fuel was dumping out of the fuel line. put the injector on the fuel line and it was spraying when I hit the start button. Changed the spark plug and it was getting plenty of spark. I have a second 420 that I took the ECM and mass air low sensor and O2 sensor off of the bike and didn't change anything. It will sputter when you try and start it while hitting the throttle so I think it something simple but not sure. I am new to EFI so I am looking for some help. Carbs are definitely easier to work on but on to EFI.
Thanks,
Hunter

Timing isn’t out is it?

Check the compression first and compare the measurement to the service manual spec. If it is within spec then check the ignition timing in case the flywheel woodruff key is sheared. Then check valve timing and adjust the valves. Assuming the fuel system is alright, its probably one of those...

Woodruff key is exactly what I was thinking, these symptoms the OP is experiencing are pretty much the same as we had with keithuk’s rancher.

Hate to be a bore but how exactly did you check the timing? Did you follow the FSM? Was timing absolutely smack bang on or out a little?

Honest opinion at this point.... Check your cam timing again.
