No start issue.

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.

any ideas on where to start?

Unplug the fan clutch and see if it starts

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.

I'm a curious sort. Unplugging the fan takes less than 1 minute ...................................... Same w/ GPCM!

If you need the heat, leave the block heater plugged in over night!

Keep us informed!

Me too.

However i I just don’t see a problem being the GPCM. The truck was starting with no issue prior to then.

Well, you have a code for it. Can you explain why?

Both the fan clutch wiring and the GPCM can cause a no-start. The fan clutch is a more common issue though.

Best of luck.

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.

So you were driving it when it died, was it like you turned the key off or like you ran out of fuel? How much fuel do you have in the tank?

I agree about the P2285 being unplugged probably caused it.

it just turned off it didn’t sputter and jerk or anything. The fuel tank is just above half I’m gonna check for fuel today.

You are on track here. I'd reconnect everything, clear the codes, and see which ones come back.

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.
