2000 Sonata will not start!! Have spark and Fuel

2000 Sonata 4cyl, one day lost all power and sounded like bad misfiring, would barely idle, check engine light came on, got the codes, and they all pertained to a faulty injector. Replaced injectors and still ran like crap. Now it will not run at all. Have fuel to injector rail, and have spark. Any ideas??

Fuel pressure? Too much or not enough?

Is it possible you put the injectors in backwards or disconnected or something?

I`m shooting in the dark here, because I`ve never had to do anything to that system on my 99 2.4.

Does it sound like it is flooding or sputtering? Or is it a consistent crank?

What was it?
