Hi guys,
I am working on my 2012 kenworth t800 and lift/primer pump is not turning on. I checked relay (by swapping with working t800) and no go. Next I was trying to find the fuse for primer pump and can't find it anywhere on the driver side. My battery box doesn't have it either. I pulled the plug for primer pump and checked voltage with ignition on and nothing.
Something to mention, I have codes for boost pressure, water in fuel and egr/scr service required. Not sure if these are related….
