03- 6.0 Cold Start Please Help !!!! - Diesel Forum

Hello all. I have studied these forums and used the info for some time now. You members are 'impressive'. I am in desperate need of help.

My 2003 6.0 with 120K miles just underwent a First Coast EGR delete manifold and a CCV reroute to the rear. I also changed all oil and fuelx2 filters. It ran great. I then installed an EDGE Attitude Platinum (mostly for monitoring purposes) and in hopes of fuel mileage increase. It ran for 2 weeks and about 1200 miles "perfect". Then one morning I went out to start and it bucked, jerked, puked and stumbled until my oil temp reached 120. Then runs great.

I changed the alternator and discovered I had one bad battery. I replaced both batteries with 850 CCA new ones.

I purchased an AutoEnginuity scan program and verified the following:
13.5 volts from system battery/alternator
48 Volts from FICM
600 to 1100 Oil Rail Pressure
Injector Buzz Test = Pass
Installed Fuel pressure gauge and am getting 50 psi.

The truck is throwing no codes. Cam and Crank are in synch but cam always reads 'zero'

I assumed the EDGE system wiped out the spool/oil warm-up program from Ford for my injectors. I set the EDGE back to 'stock' cycled the key several times, let it run and then removed the entire EDGE system. I still had same symptoms. Puke, Gag, No Power until oil temp reached 120.

I just took it to Ford and had them reflash the FICM, PCM and TCM with the latest updates. They called and said 'no luck, still same symptoms. They want another $ 150 to diagnose it.

Soooo..... Does anybody have any ideas ??????? This is my work ride and it's getting cold on the Harley

Had the same symptons minus the tuner. Had the reflash done still the same ended up being the FICM need replaced. My tech told me to get new batteries because I had one bad and he told me that was probably why my FICM went out. Check your altenators also, one could be on its way out the door and that too will cause the FICM to fail.

Thanks for the thoughts but.......

1 new alternator
2 new batteries
FICM volts = 48
FICM logic circuit = 13.5

The 48 Volts stays steady from start to drive. (Using autoEngenuity Program)

I have done every test on the FICM that I know. Have any other test suggestions ????
