Okay guys I Have 05 super duty that I replaced my first injector yesterday #7, after doing so The truck was very hard to get started again. Finally got it started but this morning Itwas cranking a lot longer than normal maybe 30 sec before it started. When pulling the hp oil rail on the left side closest to firewall there was a tube connected to the bottom that was not covered in any instructions I have I had to take out a large torx plug looked like a tube its self . Could I have unseated something when I pulled up on the rail to remove..

 

That pipe is the oil supply tube, probably should have replaced the Orings on it, some models require that you replace those tubes once you pull the oil rail. that Yorx plug was one of the dummy plugs that are known to fail, the O rings blow out, how did they look? you can get updated repair kits for them and they are relatively cheap.
Just a note you have to run the truck for a while to get all the air out of the system, if this keeps up might have to go back in there and replace some Orings.

 

Yeah probably would have been a good idea to just go ahead and update the standpipes/dummy plugs when you were in there. Might have to anyways now...
