2004 6.0l No Start
I have a 2004 6.0l diesel that has been intermittently had a no start issue. I came out today and it will not start at all. In the past, it would eventually start after quite a lot of times, but it would start. Today, nothing, been trying since 6am EST. I have no codes and the below:
HPOP: 987 psi
Oil Pressure Gauge in Dash: Reading normal pressure
Pulled Fuel Filter Can Cap: Full Fuel
Pulled Oil Can Cap: Was empty, but fills while cranking and stays full without depressing check valve. Drains when check valve depressed.
I'm lost with no codes, any help would be greatly appreciated.

What scan tool are you pulling codes with?

I wasn't mashing the button down far enough. Oil pumps in canister and holds. I changed oil, all filters fuel and oil, made sure the fuel and oil both pumped in to the canister, and still nothing. No start, no codes. I'm not sure where to even start looking at this point. Any help would be greatly appreciated.

davlan88, I also have a 2004, 6.0 that would not start this morning. First time since I have owned it. I have not had the chance to put my scanner on it but I did come in and check videos that I have and I came across this one from the late DieselTechRon.
If the link does not make it , try searching for "6.0 no start lacks power stalls no codes set". That is where I am going to try when I get out to my truck. I am curious, let me know if Ron's hint about disconnecting the ICP works in your case. Sorry if I double posted.

I'm thinking it might be the cam position sensor. The no start was intermittent at first. It would start eventually, but throw a cam position sensor code. It would happen about eeery 3 -4week, but would eventually fire. i figured this was for over cranking as it would eventually start after 10-20 mins. Now I get nothing, been trying since 6am. I'm going to replace the cam position sensor and see what happens. Anyone have instructions on this and is it easy to get to? I believe it's on the driver side lower portion of the block.

Why don't you post some data?
Cam/crank sync
FICM sync
FICM MPower
FICM LPower
FICM VPower
cranking rpms
cranking ICP pressure (assume that is the number you posted in your first post)
cranking ICP volts
IPR %duty cycle

It's a boost circuit, taking whatever voltage supplying it to make it 47.0 (IMO 47.5) and higher for the injectors. It's not a fully proportional circuit. The only time a boost circuit doesn't output it's designed value is when it's components are damaged. Low supply voltage damages FICMs.
From Ford TSB 29-04-3 with its new calibration.
FICM low voltage detection monitor - DTC P0560 stored and wrench warning lamp illuminated when PCM VPWR PIDS is below 10.25V for 60 seconds or below 9V for 4 seconds.
Those are the thresholds when you're about to lose it. VBatt shows you were down to 9.2v, what about earlier?

It doesn't matter the type, brand, age or what they are replenished to at first, the continuous cranking will deplenish the battery reserve capacity and voltage will drop. When the voltage is too low the circuits in the FICM are overworked trying to provide the stepped voltage they are designed to do.
