I have worked on old gas engines but new to diesels and willing to learn. I had some work done on the truck in September; glow plug #1, Injector #1 and #7 due to no power, shutting down, running rough etc. Since then I continue to have some of the same issues on and off but the dealership wasn't sure when they could look at my truck even though they did the work. Not very happy with them! Two weeks ago the truck shut down and won't start. It throws a P2285 code so I replaced the ICP sensor but still won't start. Just cranks. So very frustrated and live in a small town. Don't trust any of the mechanics here as both times they have worked on my truck I've had more issues and they don't want to warrant the work.
