Let me start by saying sorry, because i'm new at all this forums stuff but i can't find help anywhere else. My check engine light came on 2 days ago so i went to autozone to check the codes. Came up p0678-glow plug #8 circut fault. How do i check this or test this or take it to dealer? I worked as a real mechanic on big boy trucks doing maintenance/overhauls, but this is the first one i have owned and need to drive to work the next day. I know this is alot but like i said this is my first time

For what it's worth, any glow plug fault I've ever had on any 6.0L has always ended up being the glow plug control module itself being faulty, even it if flags a specific cylinder.
