Another 6.0 won't start

Arrived at work and all was well, went to leave and just cranks and cranks. I read alot of the other won't start threads and tried some stuff but still nothing. I have a 2006 F250 and here is what I tried:
FICM = 48v key on and 48v cranking
Fuel pressure good.
The ICP to my understanding on an 06 is on the passanger valve cover? I did pull it out and put in a good running 6.0l truck, an 07 F250 and it started fine but after reading more, the truck will start without it plugged in. Not sure what else to check and ready to call a tow truck. I charged the batteries with a trickle charger and both are good and have a full charge. I do not have a good scan tool to see the fuel pressure and oil pressure. I just cracked the fuel line going into and comming out of the fuel filter and got lots of fuel.
Thanks in advance for any suggestions.

Re: Another 6.0 won't start

wait, the truck starts with the ICP sensor unplugged?

I'd say the ICP sensor needs replacing

Re: Another 6.0 won't start

He didn't say that. He said he pulled the ICP out and put it in another truck and that truck started fine. That means the ICP is OK.

Myron,
Did you try disconnecting the ICP and then attempt to start it?

Re: Another 6.0 won't start

I had a similar problem....my truck died so i unplugged the ICP sensor and it started. Well I thought the ICP sensor was bad...nope. Replaced it a no change. Rplaced the main wiring harness cause it was in rough shape...no help there. Kept getting injector 2 high code. So i unplugged the injector number 2 and the truck fired right up as normal..with only 7 working injectors but still running fine. So i am having the injector replaced as we speak and head gaskets, studs, egr delete, and oild cooler to add a few...lol Good luck and I hope this helps.

Are you getting any injector codes?

Re: Another 6.0 won't start

this could be your cam shaft position sensor or crank shaft position sensor. that would be my next step if i was doing it.

Re: Another 6.0 won't start

I would think it would start if the ICP is at 1000PSI. The only question i can come up with , is it cranking fast enough? Try this.

Yes I did and no luck. One thing I noticed is the oil that seeped out when I pulled the ICP was black and old looking. The oil on the dipstick is clean looking. Could I have a blockage somewhere in the oil system? I think it has to be somewhare in the oil system, everything else check out fine. One more day of troubleshooting then it is off to the dealer via tow truck. Thanks for suggestions.
