It sure would be nice to make sentences out of your words. Makes it much easier for people to understand.

LB7 Duramax

I have 2001 GMC 3500 Duramax, The Truck went into limp mode The code was P0088. I repaired it, the problem was fuel rail sensor was unplugged while I had it apart. Also, I changed Fuel pressure regulator and fuel rail sensor from auto zone. After reassemble, it started setting code P0087. I have 30,000 miles on Bosch injectors and the FICM. Also, dealer changed all rubber lines on the top of the engine and fuel filter assembly.
