I have a 2006 Ford F-250 4x4 6.0L Diesel. Just replaced HPOP, IPR Valve, Stand pipes and plugs, half FICM, Oil Cooler, and EGR Cooler. Truck is hard to start, and dies out and wont restart until next day. IPR jumps from 14.9% to 85.9% while cranking and ICP will not build past 340psi then falls while cranking. HEELLPPPPP!!!!
