6.0L no start lots black of smoke

[bikerted86]

Have a fleet of 2006 excursions with 6.0l. One will not start chuggs lots of black smoke and sounds like its running on one or two cylinders but never fully starts . Was told it ran fine the previous day. Had a glow plug code so I change the set with no change. Had a known good FICM module also, put that in and no go.
Heres the info off the scan tool maybe I am missing something.

Cranking
RPM 170
FP%100
FICMLPWR (v) 11
FICMMPWR (v) 48
FICMVPWR (v) 10.5
ICP pressure 1457psi
ICP (v) .61

Any help would be appreciated this trucks getting a little frustrating

Welcome to the org. Did you flash the ficm? Looks like its bad. I had the EXACT same issue. When it finally fired up, it would roll coal like a steam locomotive till all cylinders caught up. Plugged in my "just arrived in the mail" Edge CTS. My fICM voltage with KOEO eas 48. Once I fired it up I was at 24-26. I replaced the half shell and everything fixed!!!

You cant just put any random FICM in the truck. It has to be flashed to your processor/strategy.

Saposivly this ficm was flashed, does it have to match the vin of the vehicle to interface properly? Im not much of a diesel tech but I am helping a friend out.

It has to be flashed to the truck that it is being put in, it doesn't matter if it was just flashed in the other truck before it was removed it then has to be reflashed to the truck it is being put in.
