I had to do an update on my scanner and download a specific program to read my ecu and I find that my FMP runs from 44.5 to 47 for the first 5 min or so from a cold start in 74 degree temp today, then after a short ride of just short of a mile it would read from 45.5 to 48.5 volts the FLP and FVP read 13 to 13.5 volts.

My volts from alternater run 13.8 to 14 volts. Even with ac, high beams, radio on and doors open it never drops below 13.5. I dont think my alternaters are bad. It's pointing to the FICM.

FICM is low but not too incredibly low the Range is between 40-52volts before the PCM will set a DTC/CEL
Some say it needs fix at 42 volts IIRC
But its definatly starting to go Bad
If it were me Id send it in Before it gets way bad it may burn up the spool valve in the injectors if to low
Best thing here is to send it to ED at www.ficmrepair.com he will take GOOD Care of you 200-400 something like that depending what you want BEST DEAL OUT THERE
Dont get one from Ford they have issues still and are a pretty Penny 1k and up so
Oh you might be able to soilder this one since its failing for low volts might just need a reflow on a few of the joints you would have to open it up and make that desision based on what you find look in Tech folder lots of stuff on it

that 40-52Volt range is off the operating values sheet I have I beleive thats the point a CEL will turn on
Im going to add that number to my little values sheet
thanks Mark

I only get contrabution codes for injectors and some of those codes are for injectors I have already replaced. I have replaced a lot of things as a trial and error type fix. Egr delete, opt, icp, map, 2 injectors, I have the blue spring and banjo bolts to install.

Odds are once you get the FICM fixed all will be Good contribe codes should go away
Only catch to that would be if the FICM been bad for awhile and took out injectors
Best thing here is get thhe FICM Repaired and go from there
the FICM going bad will cause all kinds of crazy codes and stuff to happen
Go ahead and install blue spring and send FICM to ED wait on the rest of it I have a feeling getting FICM Fixed will SOLVE ALOT or ALL of your drivability issues

I hope so. I did get a code for a bad injector, it was #3 I replaced 4 & 6 and I get tne contribution codes on 4578 & sometimes on 6. Kind of weird but its all starting to make sence and maybe just maybe my trans may be better. I don't think so but here's to wishful thinking.

Its Also IMPOSSIBLE to diagnos a BAD Injector with a BAD FICM IMPOSSIBLE cuz the FICM Controls the injector have to fix it first
what are the Codes????
Whats the Trans doing???
I had my injector Oring Leak it would run rough till warm trans wouldnt shift right and I mean shifted TERRIBLE fixed injector problems and back to shifting smooth as ever
IDK why but injector problems cause weird trans issues get the FICM Fixed and see I would bet you 1 Buck the FICM being repaired will SOLVE the tranny shifting issues
