the rail pressure code your getting is pretty common if you're running a box that increases fuel rail pressure. i had it myself but was able to clear it after several attempts and it has not come back. the starting problem you are experiencing sounds exactly like the one that i had until i got a re-flash about 3 weeks ago and have'nt had the problem since. i don't think this version of the new software has been available that long so if you were re-flashed several years ago it might no longer be the latest version for your truck.
thanks for the info .. i am gonna call the dealer today ...

I had a similar issue with my 04.5. It would run real rough for about 5-6 seconds then clear up and run fine. I had a bad fuel injection pump. It was bleading pressure when the engine was shut off causing air to get into the fuel lines. Ended up getting the injection pump replaced under warranty and the problem is solved.

well last night .. i went and took out my quadzilla box and took out all the wiring and just left the j/a hooked up .. well first off it runs much nicer just with the juice with attitude on there ..
anyway i came out this morning to start it to take it do the dealer and she ran as smooooth as silk .. like a brand new truck and it was a fairly chilly morning also .. so i postponed the dealership visit for awhile .. and I'll monitor it .. it must be my truck not liking the quadzilla stack ...
thanks for all your guys input on the problem.. what a great form !!
