Since the code is showing up for all 8 cylinders, it's more likely an FICM related problem. It sounds like it's not producing the full 48 volts that fire the injectors. It's gonna be pretty hard to diagnose yourself, though, without at least having a scope. Those pulses are pretty quick(I think like 800 microseconds), so you're not gonna see them with a meter. I'd wait for one of the techs to chime in on this one. You might also check the voltage at the batteries. On the 7.3, you could get similar codes from the IDM from having low primary voltage. I'm assuming the 6.0 might be vulnerable to the same thing. I think the IDM is integrated into the FICM on the 6.0, though.
