You need a minimum of 500# ICP, and IIRC 150rpm cranking, before the PCM will fire the injectors. Slow starts are usually one of those two issues. On an '03 it could simply be the ICP sensor, which is in a bad location. Or could be injection pressure is leaking from the usual suspects. Load test your batteries to be sure they are cranking strong. Often can't tell by just listening.
FICM volts maybe, but 47.5 is good. Trick is to watch the FICM volts before, during, and after cranking. Voltage should hold in all those different modes.
And of course glow plugs, but the glow plug monitoring is very good on the 6.0. The GPCM is still a possibility. The monitoring is good, but not perfect.
