7.3 No Fuel To Injectors

I have fuel up to my fuel bowl, but no fuel getting into the motor because it is not smoking at all. The wires on my valve gasket have power to the glow plugs but that's it. The PCM has power I'm wonder if there is a fuse for the injectors. I am also getting good oil pressure. I do not have my owners manual so I have no idea if there is a fuse for the injectors. Help would be greatly appreciated.

the injectors will not get power for several reasons.
Most common is battery cranking voltage below 10.5
You should check fuse 30 MAXI as your fuel heater could have shorted which is common and that controls PCM
