I am,desperate ,fuel injector issue

[Atennessee75]

Hi , ok I picked up a 2011 pcx excellent condition ( other than it wouldn't start) for cheap. So im into this and I replaced fhe fuel pump and test it and the fuel is flowing too the injector good. When the injector is out of the fuel line the fuel will squirt a good 12 inches out of the tube, but it will not spray through the injector. So I have purchased 3 brand new injectors and all the same. So im thinking it a pressure problem. But I am not sure. Or is it electrical so I mess with it fill the tank up and now it will spray a little when. I'm trying to start it but it doesn't spray when I prime it or first turn the key. You can hear it running but no prime.
