P0088 Says that the fuel rail pressure is too high. I haven't been able to find out where to start to find out what is going on.

The truck goes into some type of limited power mode or something where I can't hardly accelerate and can't get over 60mph going up a hill. Seems like the higher rpms are just gone. You can go WOT and the rpms stay at 2000.

Would it be the fuel pressure regulator or the fuel rail sensor? How can I test to eliminate one or the other?

Thanks for any help.
