Is anyone else having problems with the fuel rail pressure(normal at 23,000 to 26,000 psi) dropping to 9,000 psi on the LLY :ro)and then not running over 2,000 rpms until you turn the engine off.

That is a P1093 code. Do a search on it and you will find out all about it.

I have a friend that has a flash monitor or what ever and I use it to see if it has left any codes and it tells me the psi.Your local dealer can also do it.:grd:
