Dipping below 45 volts means that your FICM needs to be repaired. Dipping into the 30's causes many a no start. Check out your batteries and your alternator pursuant to the directions on ficmrepair.com while the FICM is being repaired, but there is no doubt that service is in order. If you sent it in to us, we could load an aftermarket tune on it (do a search for Atlas 40 on here for others' comments on that one if you want) to make you fall in love with your 6.0 all over again!
Hope this helps,

Ok, I got my dashboss to work. Here is the data.
FICM SYNC = CC FICM
FICM Voltage= 48.50
ICP (key on) = 1300-1400
IPR =49%
The IPR numbers jump around as I am trying to start the engine but then settles at 49% jump to 84 then back down. Key on engine off IPR is 15%. Not sure why the the FICM SYNC says "CC FICM". Also, the FICM Voltage goes down as I am trying to start the truck. I guess that is normal?
Anyone have any ideas with this new data. Thanks for the previous replies.

Checked it again this morning. ICP Volts (Key on engine off) are .24. FICM Volts were 49. I then began to crank the engine and FICM volts slowly dropped to the mid 30's over about a minute. Could the FICM volts be dropping because my batteries have been taking an a*s kicking over the last week? I have been really working them trying to start this thing.
I don't want to do work on the FICM if I don't have too. Hate to do the work and still have a no start. Thanks

Does the Dash oil gauge show pressure while cranking.

I just had the similar problem. After a 30 mile drive the engine died and would not start. Had it towed home. I got in it and it started right up. I let it run to get to temperature and when reached temp. it died. I pulled relay #304 and it was pretty warm. I had just installed one of Ed's FICMs with the Atlas 40 2 weeks ago. While running all numbers are fine. Could it be the relay going bad?

I got it Ed. the plugs to the FICM had worked loose. Apparently I had not pushed them in far enough to click them in place. Runs like a champ. The Atlas 40 did wonders for the ol 6.0.

Glad to hear it! Yup, getting the connectors to click in is a big deal (and often a pain in the back side!).

Mustang 309
Key on Engine Off
FICM SYNC = CC FICM No Sync
FICM Voltage= 48.50
ICP PSI =Starts at 0 the first time I start KOEO
ICP Voltage = .24
IPR =15%
Key on Engine Cranking
FICM SYNC = CC FICM
FICM Voltage= 48.50 then slowly goes down as battery starts to die. Goes to mid 30’s
ICP PSI = 1300-1400
ICP Voltage = 2.30 then goes down as you crank
IPR % =49% Jumps around never over 85
RPM = around 250 tries to start then spikes to 320 RPM
The funny thing is it tries to start….once it tries to fire up it throws black smoke out of the tailpipe. I have never had this problem with this truck.

This may not describe your issue exactly, bit here is a link to a thread that ended up being a bad alternator/FICM.
https://www.ford-trucks.com/forums/1293492-help-4.html
It's a bit of a long read, but it just shows how the charging system can cause all manner of issues if it starts to fail on you. I really hope that you are charging up those batteries, low batteries will toast your poor FICM, it's overworked as it is.
