fixed ficm still have white smoke-what next

ok so ill start from the beginning and see if anyone has any ideas .2004 f350 130k miles-banks six gun,airraid,mbrp dual cat back,arp studs

ive had a harness issue for some time,on occasion i will get a no start.i found if i jiggled the thick part of the harness that runs down the drivers side valve cover,she fires right back up.this has gone on for at least 20k miles.acouple weeks ago i had this problem but i did my thing and sure enough she fired right up and i was on my way.later that day i came out of a parking lot and my truck stumbled a bit and puffed some black and grey smoke,was alittle hesitant but she made it home just acouple miles.at that point it threw a po405,so i cleaned the egr and she ran fine,but smoked like a freight train(white,kinda grey,but smelled like diesel,i think at least.o yea by the way i have had my arp and my gaskets done,as well as oil cooler and egr about 30k ago.i do run mbrp cat back,banks and airraid intake,thats it.)
temps all seemed fine eng temp 186 eot 191.even after the smoke the truck still ran fine.i then parked in my driveway nose doen and let it sit and cool down overnite,there wasnt a puddle but just a bit of moisture on egr,couldnt tell if it was coolant or raw diesel.(looked like fresh motor oil)i decide to check ficm,got over 45 volts at key on as well as running.after test the truck seemd a bit hard to start.at this point im very lost and confused,as originally i thought egrcooler and oil cooler.so i did what i had to and to the dealer she went.now after there diagnosis,they have told me all systems seem normal,injectors,egr,oil cooler,etc....they did unhook the banks.but they say the ficm is bad,told me they could get it to test bad.i followed the steps to test,so i thought.they told me i needed to test with a 10ohm resistor.is this correct?needless to say they told me $1400 plus the 230 to troubleshoot.told them i didnt have that much and he proceeded to tell me they would put it back together for me,he sounded annoyed.i let them know about the harness issues and everything else,they told me almost $3000 for harness,ouch.

1.could it be just the harness causing my problems?
2.did i check ficm correctly?
3.if its the harness is it something i can change myself,and they told me
the harness is 1 piece.i have found ficm harnesses as well as main
and injection harness on ebay.are they the same?

im so lost and having a bad time finacially,any suggestions would be great.

ok so i got the truck back and fixed ficm,nowi get a contant 48.4 volts.but she still smokes,only codes were 403 and 405.what else would cause this smoking,smells more like fuel not coolant,doesnt seem to be overheating or burning coolant in the short runs i take.

I am having the same problem. At a stop light I feel sorry for the person behind me because I am gassing them out. The smokes seems to die down after I get up to about 40 to 45 mph, I guess it could be cause I can't see it but don't know for sure. I am puzzled. Have you gotten any new information since your post.

Unhappy

I have a 2004 6.0 bullybog with outlook. normally run at 25 to 50% boost.
I am having some like problems. There has been cold start problems for a while. I thought I fixed it by plugging in the block heater.
A friend at the dealer said FICM. I sent it to circuit board medic for repair. It did help.... but now. I still need to plug in. Sometimes it starts right up.
Other times nothing! lately it may start when I sit at a light and go to take off, you would think I was burning coal. Sometimes when idleing it will just shut off.

I have a 2004 late 6.0L and the Bullydog with Outlook set up also. I have had the stock tune in it for about a month trying to troubleshoot this problem. I keep setting an 0611 on my Bullydog Outlook but am not getting a CEL. I used a multimeter to check out my FICM and it checks good with KOEO and while running. I know its running rich cause you can see and smell it, I just need to know why so I can fix it. I am running out of options and may be forced to take it to a specialist.

I found a shop a hundred miles away from me. (Little Power Shop) in Bradford PA. I made the trip to talk to a "real" Tech. I learned more from him in 5 minutes than several weekends of searching the internet. I have cold start issues. When warm and idling it will just turn off.... AND the smoke.

The smoke is bad EGR. He can do an EGR delete without the kit. He welds a cap over the heat exchanger plus the other stuff. The idle he said was from a high pressure oil leak. When warm and idling the oil is thin and not enough pressure to switch the injectors. He has a flash for the FICM to help the cold starts. He is also going to upgrade my air intake.

FICM must be a common issue says he changes a few hundred a year. I saw a pile of them while I was there.

He had a motor out and torn down. He was showing me as he was explaining. Wish I would have found them last year when this all started. My appointment is in 2 weeks... BOY... I hope I can get this fixed for the money he quoted without finding any more problems. Much less money that I feared!
I ask about the high pressure oil pump. He said a new one is about $600.00. Would not change it unless it is bad. I see some of the posts saying to change it while down there... but it is another $600.00

Good Luck and I hope it works out for you. I have ordered a EGR delete kit and oil cooler which should be here any day now. I will put it on next weekend but that is only part of my problem. I still will have to troubleshoot the running rich (blue/grey smoke) at idle and low speeds.

I have had the white smnoke problem on many occasions and 100%v of the time it has been a leaking injector. Basically, you have to have the truck analyzed on a computer when it is dead cold. That is the only way to determine which injector is falling off. Once it is warmed up, the injector works, but is leaking diesel so thew cylinder is burning the diesel inside the hot exhaust manifold and creating not totally burnt diesel in the form of heavy white smoke. If the smoke smells like coolant, then you have other issues. However, you shouild have blocked off the EGR up-pipe by now to avoid expensive EGR and oil cooler issues.

look for the spot worn on the harness and tape it up that will stop that part of the problem.
