In the morning the truck does not start?

In the morning the truck does not start. After it starts it will run good all day but in the morning will not start . I have a new fuel pump new filter , new relay, box coils. It is like over night the gas goes back down the fuel hose away from the fuel injectors. It will drain the battery trying to start it. Spray starting fluid it will start then stalls. I will give up go away come back in an hour and it will start wright up. Everything is new, I do not know what it could be.
