2008 Rockwood

My 5.8 will not start. It was running just fine and died and hasn't started since. It has spark. 40lbs of fuel psi at the fuel rail. I've checked the ground from the battery to the fuel relay and fuel relay to the brain. Checked the ground from the cab to the brain box. Both fuel pumps are running. I have voltage to the injectors. I've checked continuity from the brain box to the injectors its good. I've cranked the engine a lot since it died and there is no gas on the plugs. So obviously I'm not getting gas to the cylinders. In my opinion the brain box is not sending the ground to the injectors. Is there a sensor that would keep the brain box from sending the ground to the injectors? From what I understand there is always power to the injectors and the brain box sends a ground to the injector when its suppose to fire.
HELP PLEASE!!
