You ain't gettin a high pressure fuel pump changed on a 6.4 for $800.

Very disgusted with this going out so early and I worry I will have this thing draining my finances as I am running lean this Winter.
Temps had got down in the single digits the night before.
Lift pump should be covered under diesel engine warranty to 100k miles.
Check fuse F1.74 in the underhood junction box and see if it's blown. If it's blown the under fuel pump harness has chafed against the pump and caused this problem.
