6.0 throwing P0403, 0405 and sometimes 0611, wont start

[rfishbone]

Hey guys,

I ama new member but a lifelong diesel owner. I have a 2006 f250 with 167k on it. Three days ago it gave me a real hard start out of nowhere so I scanned it and it threw the codes for the crank position sensor and the cam position sensor. I replaced both of those last night and it still wont start, now throwing P0403, P0405 adn it hit P0611 once and then not again. I know about ICP sensor problems but it isnt showing the code. According to my book both of the P04.. codes have to do with the exhaust gas recirculation control unit curcuit and the 0611 is for the internal fuel injection control module.

I have an EGR delete and run an SCT livewire, turbo back 5" and thats about it if that makes any difference.

Any ideas would be great.

Thanks in advance

I was curious if it was the ICP so I did another long crank w/o a start and my oil pressure is reading normal....

Disconnect the ICP sensor and crank it over and see if it fires. If so, your ICP is bad.
