2014 honda rancher won't start

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.

Since it has never been running while in your possession, I would check ignition timing and valve timing in addition to checking compression. You seem to be getting fuel through the injector, so I would focus on the things I mentioned before investigation fuel further.
ok well this is probably a stupid question but I looked up ignition timing in the service manual and it showed using a timing light and having the bike running but how would I check that if its not running. Is it checking the coil or what? im just new to some of these electrical things so im trying to avoid messing up
you don't need a timing light. all you need to do is follow the sticky on how to set and adjust valves on any 4 stroke in the repair section, if you follow that ?, then its home free.
He was inquiring about setting the ignition timing, not the valve timing. To use a timing light on an engine that isn't running, just turn the engine over with the starter while using the timing light.
