According to Scan Guage's website the first of the four codes I listed (which matches their code) is...
"FICM signals for Camshaft and Crankshaft positions are in sync"
So if my crankshaft sensor was out how could this be in sync since my reader shows 0 with key on and 1 while cranking? This is why I think I may have the wrong code for this sensor.
thats my confusion. Since the FICM sync is derived from the PCM cmp/ckp sync everything should be in sync.
IIRC there should be only 2 sync PID's, cmp/ckp sync at the PCM and cmp/ckp sync at the FICM
Cheezit gave me some feedback. He said that the rpms DID come from the CMP. He assumes that the manual was misleading in the terminology (ie when it says engine speed comes from the CKP it doesn't mean rpms at the tach).

Thanks for tracking that Info Down Mark
Those 2 Bibles contradicted each other IMO
After I read your Links and Mine I was confused at that Point Thinking it could go either way
really in a sense the CKP & CMP sensors are checking the Same thing to a Point

If you had the wrong code it wouldnt display 1 or 0 But would be Blank
And its definatly Tougher since your trying to set up the SGII on a Broken truck
I'm confused.
If the FICM is in sync the pcm should be in sync since this is where it gets it from.
Why are there 4 sync codes? Shouldn't there just be 2? 1 for pcm 1 for ficm?
Diffrent codes work for diffrent Year trucks
And yes in the end only 2 sync codes will end up working
CMP/CKP Sync
FICM Sync

No Offense at all In fact its a Great Idea to find someone else with an 04 and see what codes they are running
Im thinking if your getting a 0 or 1 display for either FICM Sync or CMP/CKP Sync you have the right Code
So as you crank FICM Sync shows 1
and CMP/CKP Sync shows nothing right
I guess in short what ever one shows Nothing (Blank) we need to find a diffrent code once we get it to display 0 or 1 we have the right Code and if it stays on 0 theres your problem

What one shows Nothing
Okay, I hope I can explain this without messing things up....
Initially, there were two syc codes in the list you sent me. All the numbers were the same except for the RXD code.
This one shows 0 with key on and 0 while cranking. This code is not listed on Scan Guage's website.
SYC Camshaft & Crankshaft in sync (1 = in sync) (AlternTXD: 07E02209CD RXF: 0462050906CD RXD: 3001 MTH: 000100010000 NAM: SYC
This one shows 0 with key on and 0 while cranking. This code is not listed on Scan Guage's Website.
I then took the code from Scan Guage's website that says "FICM signals for Camshaft and Crankshaft positions are in sync". It also has all the same numbers except for the RXD which is 3601. This one shows 0 with key on and 1 while cranking.
In your earlier post with codes there was another one that had all the same numbers excpet the RXD which was 3701. This one shows 0 with key on and 1 while cranking.
Interestingly, none of these come up blank. But only two of them change while cranking. I had a thought while typing this, is it possible that Scan Guage only lists the "FICM signals for Camshaft and Crankshaft positions are in sync" because if either the camshaft or crankshaft sensors weren't working this wouldn't be in sync? Hence the reason they only show one code? If this were to stay at 0 then you would know it was one of these two causing your problem? Just a thought.
Sorry for the long answer, just trying to provide all the info I can in hopes it helps in some way. Thank you again for helping me.
But another thing comes to mind about these sync codes
Being that FICM sync and CMP/CKP sync are coming from the same area in the PCM or whatever you cant have both displayed at the same time on the SGII depending what version SGII you have.
yours being newer might display both sync PID at the same time
Just like if you were to put EOT on the screen in 2 spots only 1 will display and the other is Blank
That how James D at SG told us
I wouldnt think you could acheive FICM sync if CMP/CKP was not in sync but not shure
the problem is there was a TON of codes when all these gauges were made for diffrent year trucks ect.... and so I really dont know what codes are Good vs Bad

I just copied this from my earlier post. Thanks for looking into that for me. The entire numbers are about three posts ago if you need that.
Well gentlemen, I think I may have found the problem. I went out and did some further testing today as I really need to get my truck running. Here's what I found:
1. My FICM logic fuse was good.
2. Tested my cmp at center connector of PCM (pins 31 & 43), had reading of 1.331 & 1.332 hz. According to other posts that is good.
3. Tested my ckp at center of PCM (pins 30 & 41), tested twice and stayed at 0.00 hz.
So I'm going to pick up a new ckp sensor and get it installed. Not looking forward to that as the instructions make it look like a real PIA. But if that's the issue I will be glad to get it done.

Hi Mark, thanks for checking back. I went ahead and purchased my ckp sensor on Friday. When I went out Saturday I figured I would double check all of my readings. This time I received the proper readings from both my cmp and ckp sensors. Scan guage shows ficm sync. Still no start.
So I hang my head in shame as I type this but I can't spend any more time on this and I don't want to just throw parts at it. Last night a buddy of mine (inverted99 on FTE) and I towed it down to the dealer for diagnosis. I bought a coupon book from them about a year ago for $200 that gives me 5 oil changes and one free diagnostic. I figure this is the time to use it. They should get to it tomorrow or Tuesday. I will post the cause when I find out. I hate to let you all down after the help and input but it's been a week and I need my truck.
Just got my call from the dealership. They're stumped. He told me the tech working on my truck has been their diesel guy for 20 years. According to all the tests he ran my truck should be running. This makes me feel better, at least I know I gave it my all and the tech has no answer either.
They suggested the problem is bad ficm (even though they show 48v too), a wiring issue or... get this.... ALL of my injectors went out at the same time. Now to be fair the service guy said that was a real long shot but he threw it out there as a possibility. I told him I thought the Ford software did some type of buzz test on my injectors, he said he'd look into that.
So, I burned up my 1.5 hour free diagnostic and they tell me it's going to be $360 to pull and test the ficm and to begin testing the wires that go into the ficm to find where the problem is. . They tell me the $360 will tell me what's wrong. If its the ficm I'll have to pick my truck back up and send it to Ed. No way am I gonna pay the dealer ficm fee.
