Need help with 04 6.0
I have a 2004 6.0 with 200k miles. Was running great till last weekend and the it was like have the engine shut down 1/2 the injectors. It's not throwing any codes. I change fuel filters just in case and drained the water separator and had minimal water. The ICM is right in the middle of Ford spec. Pulling me hair out over this. If I lost 1/2 the injectors would it through a code? Never heard of anyone loosing that many at once. It is stock other than egr delete. No apparent head issued. Just not injecting fuel the way it should. Got it home, had plenty of boost. Hopefully this is something someone here has felt with and point me the right direction.

No you can have codes with out the check engine light being on including injector contribution balance codes. The scangauge is a crappy code reader stop by an auto parts store and use there code reader and see what you come up with or stop by a shop and have them scan it some places will do it for free. I would seriously doubt you lost a bunch of injectors at once. Hopefully a mod will stop by and move this to the 6.0 section for you be ready to provide those guys with some numbers from that scangauge.

While you're figuring out how to get it scanned... check the plugs on the bottom of the FICM and make sure they're clicked all the way in.
If one of the clips was broken and the connector backed out you can literally lose a whole bank at once, but this is a long shot because the truck would run horribly if at all, and I'd think the CEL would get set for something that drastic.
You should also enter the ICP_V code into the ScanGuage, to see what the sensor itself is reading. It's been while since I used my old SGII but IIRC the ICP pressure code is desired and not actual. So you're seeing what the PCM wants but not what the sensor is reading.

Our 6.0 was showing cylinder 2 misfires codes, but no check engine light. Then changed all injectors on drivers side, didn't plug ficm properly. Broken tabs. And on restarting got cylinder contribution codes on cylinder 5. Took two more attempts to get ficm plugs properly seated. All again with no check engine light
We use an iPad app called Forscan, cheap to buy, and also need a obd wifi adapter. Get them both for under $40.00

Yea, I know. Looking up a obd scanner for usb and windows now and waiting on FORSCAN to approve me for the program.

well, got it scanned and turns out the wiring harness to the injectors went bad. 4 out of 8 injectors not firing off. ordered new harnes and while i was at it upgrading the FICM to a 58 volt. also fixing a small oil leak i've had where the filter tower bolts to the oil cooled. been leaking since i replaced the oil cooler 2 years ago. figured while i was tearing into stuff, might as well fix it.

Unless it's made by Bullet Proof Diesel, the 58V FICM is 100% a gimmick IMO. The BPD one apparently uses a custom designed billet heat sink and a 5th (and 6th?) power supply to up the voltage, that's a real re-design. Some other 58V units just cram more into the original setup, increase the heat factor, and burn up the same way the old one did.
The injectors were spec'd to run at 48V. If you for some reason feel the need for 58V to overcome stiction or advance timing, or whatever the root point of the 58V upgrade it, then the FICM isn't the place to be putting the band-aid for that problem.
Were there soft codes set for the whole bank? How'd the narrow down to they harness, and not a connector?
