05 6.0l Starts and dies

Hi guys, I have a 2005 f250, i pulled out of the driveway this morning and it died. It did restart once or twice, idles for a few seconds and dies.
I only have a codes reader, U0105,U1900,U0306,P1000,P2617. Some or all will reset just from cranking.
I have 49 volts at ficm, key on and cranking. Fuse 22 is good,and ficm relay is good. Oil pressure gauge moves to 1/2 when cranking.
I can bring home a snap on modis tomorrow, just wanted some preliminary advise, have to go get a chain and drag it back home.

Dave

Lets find out what the ICP and IPR readings are when its cold with just the key on, while trying to starting cold, when warmed up, and trying to start when its warmed up.

Here's some reading;

No start issue? Look here.

You can pull the upper fuel filter and see if it is empty. How much fuel is in your tank?

Lets at least get, the IPR and ICP readings while its trying to start, if its a failing ICP sensor you can unplug the ICP and the ECM will default its readings and allow it to start without the ICP sensor inputs. IPR will tell us what duty cycle its trying to achieve to create enough High Pressure oil to start the vehicle. Once we eliminate the High Pressure Oil system we can move on to other things.

IPR. 50% cranking
ICP 1.2volts cranking, up to 2 volts
ICP pressure 1691psi cranking, 920 when it ran for 3 seconds
ICPDSD pressure 1600 cranking, 900 when it ran

Still sets codes U0105 and U0306 every time, even with KOEO self test.
Can read 48 volts at ficm with scanner(snap on modis)
logic power, main power and vehicle power reads 11.2 with scan tool.

I think the Ficm is ng?

Looks like your batteries or alternator is going out. The FICM FLP and FMP (or whatever they are called) should be 12V. Vehicle power should be over 12.5.

Had the batteries load tested? Is alternator putting out juice? Should see 13.5 volts from the alternator...
