www.ipdusa.com sells the correct shop manual for the car. It is only available in the British publication, so you will need to look up metric conversion formulas, which are quite easy. I have this book, so you know.

All pre 2008 powerstrokes use oil pressure supplied by a High Pressure Oil Pump(HPOP)to activate a plunger setup in the injector to inject fuel into the cylinders at 21 PSI. More than likely some of the HPOP components need to be replaced- i.e. valve, regulator, seal, feed tube...or the pump itself. I've replaced seals on these units since 2003, when Ford wanted to replace the pump and injectors. Did you notice a gradual increase in hard starting conditions? Do you have any visable oil leaks? Did you run the crankcase oil level down to below the add mark recently? All of these could be a factor. Ford wont tell you anything about a price because they dont like to do that before they do a diagnostic check on it and determine exactly how much needs to be fixed. Test alone will run around 100 buxs. If you are within warranty requisites then it wont matter and you likely wont be charged anything. If they crack into it have em fix as much as you can while theyre in there, because after warranty is out you are looking at a 3000 dollar repair bill from your friendly Ford dealer. Good luck...i hope this helps.
