Engine running on three cylinders

I've got a '95 Mystique and just put a new head on it. But cylinder 4 is not firing.

I found out there is no power to the fuel injector. I found that the first three injectors have a common power feed but cyl. four has a different power feed. Is there a reason for this, is that injector controlled by another sensor or is it in some kind of limp mode??? I'm lost on this one. Any help would be much appreciated.

Thanks
Brad

Id check your fuel injector harness and make sure the wires arent exposed. It could be causing it to not be running at all.

Thanks for the reply, Yes I did check that and it all looked OK. I even ran 12 volts to the injector to see if I could get it to work and that didn't even work. I did swap injectors so I do know the injector works.
