I took it to ford dealer,ended up head gaskets, and a glow plug control module. Fortunately it was still covered under the 100K engine warranty. But previous to this, I had just changed batteries. (a week prior to going to ford) Once it was in the shop the first thing they said I needed was a new alternator.:argh:over $400:argh: 'cause my voltage was still to low to diagnose. The day I picked it up and ever since I've had P2552 on my livewire.FICM Issue. ford hooked it up again, still can't pull any codes, Still hard to start, Had to jump it to get home this afternoon.:argh::argh: Still sounds like a FICM issue. I'm not sure if your warranty has expired yet. But if so here is a thread from another site that might be helpful. It's my next step.

That is the first time I have heard off a way to test out a ficm without you getting a code first. I will be trying this in the next few days. Thanks

almost sounds like you lost an injector.:argh:

I did an "injector buzz test"? with the scanner and everything passed...

Did you check the screw on the FICM with a multimeter? Check with key on engine not running, check when injectors are buzzing, then with engine started. J ust did mine today. I had 48 volt w/ key on, 46 when buzzing, 41 when running. Removed FICM, took it apart, solderedit like the 1 thread said. I then put it back in the truck. I did the test again, 48 volts key on, 48 volts buzzing, 48.2 when running. I haven't road tested yet, But the injectors are buzzing louder again.:tu::c:

Let me know if that helped you out and how your trucks runnin now...

Truck seems to idle smoother, still takes about 8 seconds of cranking before it fires up though. :argh: I also still have P2552 code,:dang: I haven't figured that one out yet.

Have you gained any power back?

crewed powerstroke 01-20-2010 03:02 PM

Seems to have the power back.:tu: I'm afraid to press the small pedal too far toooo quick; as I have just recently dropped a grand for new sneakers on it. :ouch: Did you take a multimeter and check the voltage on the screw head? It's real easy , remove the 2 screws on the degas bottle, slide out of the way a little, remove the 2 screws on the cover, remove the cover, then get someone to run the key while you check with the meter.:c:

I haven't yet but i'll have to ASAP i've lost power and i'm gettin shitty MPG and when the engine temp it below like 150 i don't have any power at all. i need ot figure this out so that seems like the easiest first thing to test and it seems like re soldering it will be easy if thats the problem
