Ok after emailing back an forth with mike from spartan diesel and talking to the tech working on my truck. I decided to go ahead and change the hpfp. The injector is out of spec. I'm getting the repair done cab off. To have one labor bill i'm having them put head studs in and they said it was no problem to do the egr & cooler delete. We believe hpfp pump is failing hence the change of pump and since one injector is acting up and needs replaced I'm just going to have them all changed. Figured again one labor bill and since one is out of spec and with failing pump others might not be far behind. Is there anything else i should consider while the cab is off? Thanks for all the info and help.
