You need to watch FICM voltages. KOEO, KOER should both be around 48 volts.

 

i have the same problem with mine i tested the voltage while it was off and it was 48v but when it was running it was at 44-45v, after driving on the freeway for 45 min+ when i hit the off ramp and slow down it dies and wont start unless i shoot it with either would the FICM cause this problem also?

Don't use ether on these trucks. The glow plugs will light it and blow the heads off. Not safe.

You can find FICM's on ebay, craigslist, and on the forums in the classifieds.

Testing them and self repairing them isn't bad (provided you can solder or know someone that can, carefully). Detailed FICM Repair Procedure - Ford Truck Enthusiasts Forums

Begle1, yes I know Innovative diesel offers three different tunes for FICM's, PowerHungry offers one, Swamps is modding them for more voltage, slightly different approach there. From what I understood the Phalanx was supposed to be able to tune the FICM through the OBD port with the programmer itself, but last I knew they were in beta testing around last year and still have heard nothing.... Not to mention they're double the price of the SCT's, and there is no support... so to speak.

 

Hello:

Doing an Internet search for a part my mech. could not find (2005 6.0 Ford FICM) I found your web site.

Read every thread, and followed the link in the post above mine, and read every post in that thread.

I called my mech. and told him I was picking up the bad part (showing twelve volts or some low number) and I followed the instructions and diagrams for repair.

Not easy, and in some ways, delicate work. I spent about an hour on the project with a hair dryer to melt the goo International placed all over the circuit boards, along with a dental pick to pull it off. Then I re-soldered 14 key points they showed to repair.

Today my truck is running great, and I saved $800 on a part I was able to repair myself.

Thanks so much for your web site!
