2250 low rail pressure code

Thanks rawze! The engine has 300k. I bought it at 285k. He is on the way to the shop with it now. I have a very good friend that is he service manager at a local international dealership. I do all maintenance work and normal day to day stuff myself, but he always puts in my clutches and things of that sort. I have been pleased with all of the work they have done for me in the past, and one guy in the shop always works on my trucks. He said that he would go down the cummins diagnostic tree to find the problem, and this shop is usually pretty thorough. Just asking, do you agree with taking it there since I trust them? Time is not very friendly to me as I have 3 other trucks and run a piece of machinery on our logging crew. Thanks very much for your input!
