2007 6.0 starts then stops 5-10 sec later, -Good base oil psi -Fuel stays at 60 psi -Batterys good/ cranks fast -FICM stays at 48 vdc -Air tested hi-psi system, no leaks -New IPR valve, CKP/CMP stays sync, -RPM signal above 200, -IPR stays at about 25%, -ICP is about 6-700psi, doesn't lose the ckp/cmp signal, or at least the scan tool doesn't pick it up. Swapped the FICM with a good one. I am completely stumped, wondering if anyone has any suggestions on anything else to look at. Just seems like I'm missing something basic but all the basic items check out good, just wondering why it won't stay running.
Any help would be appreciated, thanks alot.
