I am a new member here, some of you may know me from Dieselplace but I replaced my glow plugs and overrided the cold advanced timing/high idle to a 12v source (my switch is bad and don't feel like paying money to replace it) so I am hoping those two ingredients will help my cold starts. I was having a VERY difficult time starting up in 40 degree temps. I replaced 4 of the glow plugs so far with AcDelco 60g GPs (will replace the others when I head to my folks place in a week) and I will not be able to plug in my truck this winter so I was wondering if anybody has advice on extending my glow plug cycle through a switch of some sort. Thanks for the help.
