Update is it needs a new grille, fog light and front bumper (slightly twisted) checked out by a licensed rebuilder. For the P0087 code (low fuel rail pressure) a Duramax specialty shop diagnosed bad CP3 pump after plugging it up and going through several test. It also has power steering pump/power booster issue that will be addressed while in the shop for the CP3 pump. Even with low pressure it drives pretty peppy a lot more quieter than the 6.0L's I'm used to but I stopped driving it until it is fixed.
There are some good test for checking out a CP3 pump. But if fuel filter has not been changed the tests mean nothing. If you have not found
Deisel Place yet. You will find lots of information on all the Duramax's.
