2005 6.0 crank no start. Tons of Codes

[okie83]

Come home for Christmas and my dad asks me to look at his truck. Its a 2005 6.0 that will crank but wont start. Take about 20 seconds for the oil pressure gauge on dash to come up. For the past few months the truck was hard to start when cold and would have to warm up before it would move. Over the last week the truck would die, after a minute or two the truck would fire up and run fine. I guess this would happen a few times a day. Finally the truck shut off and its dead where it sits. Like I said it takes about 20 seconds of cranking for the oil pressure gauge to come off 0. The FICM voltage is 47.48v according to my scan tool.
It has to following laundry list of codes:

P0261 Injector Circuit Low Cylinder 1
P0263 Cylinder 1 Contribution or Balance Malfunction
P0264 Injector Circuit Low Cylinder 2
P0267 Injector Circuit Low Cylinder 3
P0270 Injector Circuit Low Cylinder 4
P0273 Injector Circuit Low Cylinder 5
P0276 Injector Circuit Low Cylinder 6
P0278 Cylinder 6 Contribution or Balance Malfunction
P0279 Injector Circuit Low Cylinder 7
P0282 Injector Circuit Low Cylinder 8
P0284 Cylinder 8 Contribution or Balance Malfunction
P0528 Visctronic Drive Fan Speed Sensor Malfunction

Im going to start messing with it in the morning but wanted to check here and see if anyone had any ideas.
I am a Diesel Mechanic by trade but most my experience is in OTR engines and the last year has been nothing but CAT 3512s and MTU Series 4000s
I have had the heads off a couple of 6.0s but havent ever had to do any diagnoses for problems likes this.

Thanks in advance

FICM is junk.

This is a link to how to check a Ficm. YouTube
It sounds like at least a Ficm.

Are you just checking the voltage with the key on? You have to check it while cranking to get an accurate voltage.

Batteries AND ficm is junk, possibly alternator.

Sent from my phone that somebody didn't help me get.

Batteries were just replaced with Interstates less than a month ago. FICM Voltage was while cranking via scan tool. Not at the FICM

Check at the FICM. That's about the only thing that will cause all low circuit injector codes.

Pull your secondary filter, hfcm fuse, and ficm relay, crank it over and see if you have combustion gasses/bubbles entering the filter housing.

Ok I will check both of these in the morning.

Can the FICM be bad and still show good voltage while cranking? I ask because I checked this few months ago when he first told me about the hard cold starts and the voltage was good while cranking.

Also who do you guys recommend for FICM repair.

Usually you will see low voltage at any stage cold, or through the driving range. Ficmrepair.com
