Hello I am new to the forum and new to these 6.0’s I’ve had mine about 4 months and haven’t driven more than 150 miles because it just keeps having issues.
I have replaced number 8 injector, hpop, icp, ipr, ficm, y pipe, oil cooler, egr cooler, batteries, belt and tensioner. The batteries in it were dead by the time I got everything done they were unplugged for like a month as well
well I finally got it running the other day and I was driving it home happy as can be, when it just died and wouldn’t restart. I unplugged the icp and it still wouldn’t start. I borrowed my buddies monitor and found all these codes p0480, p0528, p0603, p0670, p1000, p132b, p2285, u0105, u0306.
If it doesn't start, then leave it unplugged and unplug the GPCM and see if it starts. If you live in a cold climate, then leave the block heater on for 4-5 hours before trying to start.
P132b indicates that there are issues with the turbocharger, MAF sensor, MAP sensor/hose, IAT2 sensor, intake leaks, or exhaust leaks, etc. Frequently it is a sticking turbo issue.

will do the fan and GPCM tomorrow and I know it has exhaust leaks all 3 of my v bands are bad, I am also gonna try and get some readings of icp and try wiggling the connector and double checking the ficm connectors are good and tight
I have absolutely no clue, the only thing I can think is a ground, I know there is a wire in my engine bay just chillin I can tell where it goes I just need a bolt but from what I’ve read it’s not a ground? Doesn’t make any sense to me
You have two codes in that list that are most troubling - the P2285 (not enough oil pressure) and the U0105 (lost communication with FICM). Do you have gauges to see what sort of Injection Control Pressure you are building during cranking? It's also worth checking the wiring coming into the FICM as you've suggested.
Okay so batteries are dead after this round of testing.
However, ficm connections are tight,
icp: 2000psi cranking? Seems high to me but it’s kinda cold out
ipr:50%
vgt duty cycle: 0
map: 12
i forgot what I had for ficm voltage but I’ll charge my batteries tomorrow or swap them at work.

P2285 "probably" is from trying to start w/ ICP unplugged.
I work at cat and one of our benefits is lifetime battery replacement as long as we work there so I’m gonna swap them out today at work, but I didn’t get to check for fuel today.
Okay fuel Isn’t the issue filter look great fuels clean not gelled or anything.
Ficm: 0V
ficm sync: no
so I’m looking more into that loose ground or what I think is a ground. I need some more tools so I’ll have to get those at work tomorrow.
