It's very common to find one of the three connectors not fully seated. Perhaps that's what happened here. All three must click into place. Any less and things could work their way loose over time causing all sorts of issues.

 

Ok my volts when just key on was 36 for the first screw and 13,.5, 4 in the order of screws from drivers side to passenger. Then when starting the first screw was 60 then 14,.1,.6 so does this mine is shot?

 

Not shot, perhaps, but definitely in need of service.

Since I started the thread, I guess I can hijack it!

Ed - my repaired FICM has been working great (not in my truck, but I loaned it to a friend). Thanks!

 

I'm very glad I was able to help out, Mark! Thanks for the kind words!!

 

This is a great post. My problem started Sunday morning. Went out to start my truck and it didn't start right up. It started after a cranking it for a short bit. Ran and started fine rest of day. It has done the same thing Monday and this morning. I am getting the FICM checked Thursday. It is throwing two codes, P2284 and P2291. Could a weak FICM cause the codes? I have a March 03 build F250, 6.0, remote starter and Super Chips Tuner. I put it back to stock last night and cleared the codes. Thanks for any responses.

 

The P2284 code is typically the ICP sensor, not the FICM. The P2291 code is definitely related as it is indicative of too low a pressure while cranking. I'd have the ICP sensor changed out and see if that takes care of you. The other option is that the STC fitting came apart or that the high pressure oil rail port plug o-ring decided it didn't want to live anymore. Regardless, it doesn't sound like the FICM (as much as I'd like to take care of you if it were... ).

The thing is that I am not having any of the symtoms related to a bad ICP sensor (from what I read). After the truck starts, it runs great and starts fine the rest of the day.

 

Pull the IPR and see if the screen is compromised. P2284 and P2291 are a little different to diagnose but you definitely have a HPO problem not a FICM problem.

 

I have a 2006 F350, 6.0, 107,000 miles. I have codes P0264, P0267, P0270, P0273, P0276, P0279 and P0282. All codes read "Cylinder Injector Circuit Low" for all respective cylinders. I DO NOT have code P0611. I have tested the batteries, both read 12.4 volts. When testing the FCIM:
While turning the key on: 48.2 Volts
With the key on: 48.2 volts
While cranking: 20.4 volts
All tests were done with the negative side of the tester on the negative side of the battery and the positive side on the screw closest to the drivers side of the vehicle.
I have been unemployed for 10 months and can not afford to take this to the dealer nor can I afford to fix something that isn't the problem. If anyone can clarify that the problem is indeed the FCIM I would be eternally grateful.

I have more time than money. If this is the problem perhaps you could suggest a place that can repair the FCIM in a reasonable amount of time for a reasonable price?
If a repair is done, will the dealer have to do anything to the FCIM/Truck for it to run properly?

Your FICM is indeed bad. After repairing it, nothing is needed at the dealership (assuming you can remove it and re-install it yourself - which is pretty easy).

 

Thank you very much for your response. The reason I questioned it was after reading many posts regarding this issue, most say that I should also have the code P0611, which I do not.


I see the four bolts/nuts holding the unit to the vehicle but from where I stand I can't see any electrical plug(s). Is it on the bottom of the unit and will I be able to see how to disconnect once the four bolts/nuts are removed?

 

Yes, there are 3 connectors attached on the bottom of the FICM. Here's a link to the ficmrepair.com site.

Here's a link to a thread with testing and removal videos.

 

I cleared the codes and ran it over the weekend. I pulled the codes today and now I am getting 1 code,

P123;

Anyone know what this is?

 

Thanks Guys
I did the FICM test and repair this weekend and now my truck is back to normal. Before repair 48 volts key on and 29 volts started. After repair 48 volts key on 41 volts running.
