hey guys i need some help a couple of weeks ago my truck died with no check engine light. i called a local duramax specailist to come and look at my truck he said it was a stuck injector. we got it started and had no problem with it till yesterday. i noticed it wasnt running right. and then all of a sudden it lost all power and popped the check engine light on. put my scanner on it and it was p0087 fuel rail pressure low. how do i fix this. i have to have my truck and i cant get in touch with the guy i called last week. PLEASE help. any suggestions are helpful and appericated. im considering just changing the fuel pressure regaluator. is that a good idea. or if someone can give me suggestions to take. thanks guys for everything.
