I just went through this on my 2000 ram the guy that owned it before me replaced the lift pump,injectors,injector pump,turbo. I hooked a gauge to the turbo and had a buddy brake torque it. I had 3 psi. I hooked my snapon scanner to it and the boost pressure sensor showed 0 psi. I replaced it and the truck came back to life!! 10-15 minutes to test it and scan gotta be cheaper than throwing parts at it. Just a thought. Also I had no CEL.
