Yes they can stick open. But to rule out the regulator you should test the fuel rail pressure. I like to change the injectors as a set. Usually if one has failed the others have been subjected to the same conditions and may fail soon. Is it only number 4? If only one cylinder was over fueling it should still start (even 2). If it won't I would look deeper. Do you have spark at all cylinders?

A severely leaky fuel injector on some engines can hydro-lock a cylinder causing a broken piston or bent connecting rod when trying to start it.
