Smile 03 6.0 missing when cold

The truck missing when cold and no power but the check engine light does not come on.Even when it stopped running the other night the check engine light did not come on.It comes on when you turn the key on.It also had codes in the pcm. Can anyone tell me why the check engine light does not ever come on. Thanks

I did studs, gaskets, and egr delete this winter.. Truck started fine/ran fine when cold before I disassembled the whole thing, now all I have are headaches with it when it's cold.. I must've jarred the ficm. Problems getting worse and worse..

Mine has remained free of trouble since replacing the FICM. Knock on wood. From the sounds of the other entries Ford needs to get off the DEEP DARK SECRETS of the FICM. Or they could admit that there is a problem, then find a fix. But that's getting into politics and I don't like going there. Good luck

i didnt read thru all the post but the way to check the ficm is first you must have a scanner. The truck must be cold. I cant remember the correct temp for the oil temp to be ( i think it is some where around 60 degress or colder ) have the scanner pulled up so you can see the ficm voltage . Turn the key on , do not start.Turn the key off then right back on...If the voltage goes below 48 volts then you have a bad ficm.. Mine took a crap a few weeks ago.My truck wouldnt even start when cold unless i had the block heater pugged up.The problem is this inductive heating, when the oil temp is below 60 or 65 degress this is when it goes into the different stategy therefore cooking these ficms..Someone may have said this already im not sure as i didnt read all the post.I apologize if i stepped on anyones feet that already stated this..I currently run a different stategy tuned by php to elimanate the inductive heating. These ficms can be fixed by swamps diesel..Its alot cheaper than a new one if you have a spare to run while yours is fixed...I hope this helps .

So this "inductive heating" that I read about (not only on this thread) can be eliminated?? If you keep the truck plugged in and keep the oil above 60F it'll keep it from inductive heating?? And I have been wondering, I'm almost certain my FICM is doneskie but it runs fine once it warms up or I keep it plugged in.. Does it hurt to run the truck with the FICM not running 100%???
This is a vid of mine, it starts to act up around :45sec..

well the ficm can and will take a crap on you and the truck will not start at all..Its hard to say about cold running issues on a 6 liter could be some bad injectors..the only way to tell is put a scanner on it and watch the voltage on the ficm..You can send the ficm to bill at php or eric at innovative and they can reflash it with a different strategy to do away with the inductive heating but there are those that still have some issues with this..Even if it is getting weak it will still start...

I gotta work on one with this problem next week, but to the one who said their truck only makes it's 3 miles before dying... That sounds EXACTLY like my buddies 99 7.3, ended up being the cam was walkin around in the block... I know this thread is old but if your still havin problems check your cam...

Three very reliable sources have told me that when the FICM goes, it can take injector(s) out with it.

FWIW, my FICM died and when it was replaced with a good FICM, I found out that I also had 5 bad injectors. I don't think its a coincidence.

Ya, I've heard that a lot since I asked that question. I think Eric @ Inn. says it'll take out injectors, the guys from Swamps, and Adam at FCDP all said that they
have a tendency to take out a few injectors if the FICM croaks.
And I was lucky enough to find that my problem was a clogged/collapsed screen that lead to the HPOP.
Pulled it out, chunked it, got another one in there and it starts/runs GREAT..
