I have a 2006 6.0 F250 4X4 CC with 105,000 miles. It ran fine yesterday and this AM it will not start . New bats. new alt. no codes. SGII readings koeo ICP 1 IPR 14.4 FICM 48.5 Cranking ICP300 IPR 74 RPM 170 FICM sync yes . I disconnected the ICP and it still doesn't start. I have already done dummy plugs and stand pipe plugs. Thanks for any help I need the truck to get to work Monday.

 

Cranking 300ICP indicates a leak. You need to air test the HPO system. Do you know if the STC fitting at the HPOP has been changed?

 

No it hasn't been changed yet. I was thinking that was probably it. Thanks I will have to order one.

 

It didn't start on Friday AM but started in the afternoon and ran great all weekend. That made me think that the STC needed to be done.

 

I just wanted to update. I changed the sct fitting and while I had it apart I did a egr cooler delete and cat delete. it wasn't as hard to do as I thought it was going to be. after I got it back together it only took three tries to start . now the truck starts great cold and hot and runs better than when I bought it two years ago. thanks again for all the help.
