two weeks ago I threw code p0148. called todd at tc diesel. he helped me determine that the modded prv I bought from him three years earlier was bad. got another one from todd installed it last week. yesterday driving the truck it lost power and actually stalled. truck started back up and ran fine. but I got codes p0088,fuel rail pressure too high and code p0251 injection pump fuel metering control.truck also ran fine today to and from work. bought a new fca today but I checked the one off the truck when I got it off. it clicks when you but 12 volts to it. it reads 2.8 ohms. so I put it back on. the injectors are two years old and are 60 hp industrial injection injectors.also checked the fca plug/wiring which checked out good. whats next???? cascade overflow valve? fuel rail pressure sensor? injector connector tubes???
