Hey B,
I looked at the vac diagrams in the FSM after I finished putting everything back together to confirm that everything was in the right place, I also took pictures of areas that were busy ( around the EGR ) to be able to get everything back on in the right location, orientation and path. Everything that is on there now looks correct but I know I missed some esentail thing during reassembly because of the inability of the truck to keep running. I drove it to work, took it apart and I messed up the rebuild...Can you think of a likely area that a newbie might overlook while installing new fuel hoses onto the fuel rail, while doing the fuel pressure regulator or IACV?? A small detail like a hook / hold-down / or a missed clamp? Anyone else know of an easy-to-miss thing that wouldn't jump out as a significant problem?
