6.0 ficm trouble
 

Need some info. Replaced hpop-did egr delete. Truck would run and die when warm. But it started good cold. Did the ficm test before starting all voltage were good. Now it will not start ficm reads 1.0 volts.
Got a new manual and one of the problems were that it could be the anti theft was set off and needs to be reset.
The question does any one know how to reset the anti theft. It did go off when replacing the batteries, but cancelled it as always.
Has anyone every heard of this happening?
Have ordered the auto enquinity but do not know it will return to default on the ficm.
The repair manual says that a good scanner will reset the pcm and ficm to default, the one I have now will not.

Thanks

Once you have your AE, you can monitor FICM SYNC. SYNC is basically if the FICM is recieving power or not. It will be a YES or NO signal.

It wouldn't go from good to nothing like that. Never seen one read 1.0 volts.

Do you have any lights flashing? I though the anti-theft light would flash rapidly if this happened.

Are you sure it's just not fully bleeding out the air from the HPOP? Did you fill the HPOP reservoir with oil before trying to start? If you didn't, it could take a decent amount of cranking to get it going.

You're definitely checking the correct pin on the FICM right? Should be the top row, closest to the passenger side (by top row, I mean closest to the firewall), provided you still have a 7 pin FICM on there. :c:

From what I'm seeing though, the only way to actually reset it is to bring it to Ford, if it is indeed tripped. Even the really high end snap-on scanners can not reset this.

However, at the moment, I'm leaning towards air in the high pressure oil system due to the HPOP swap.

I have a question, the ficm in my 05 6.0 is being replaced this week. Should I be worried about other parts failing following this, like a domino effect. Some guys I know claim that that is just the start of my problems, and should sell my truck asap. I just need some feedback on this cause I don't want to sell my truck, but i also don't want to drop a ton of money either.

I hope you are not buying a brand new one, they can be repaired for less then 1/4 the cost of a new one, even the new one should be sent out to be resoldered so it lasts. There should be no domino effect, it's just some people misdiagnose a bad FICM as bad injectors and wind up replacing injectors then find out FICM is bad

Do you know of a reputable business that deals in rebuilding or sells rebuilt and programmed ficm's?

FICMrepair.com is a sponsor here... they're one of the least expensive and have a great reputation.

FICM's die all the time, it's because they're poorly built in Mexico and they use hardly any solder to attach components, so after sitting on the valve cover going through all those heat cycles and vibrations, they fail. It will not domino anything. Typically the only things on a 6.0 that cause domino effects are weak batteries (leads to killing the FICM sometimes, and possibly injectors) and the oil cooler plugging (leads to blown egr coolers, and blown headgaskets)

Thank you for the info, I really appreciate everything!

Also check your FICM fuse. it is located in your under hood relay box. (15a fuse)
