Somewhere I saw a picture with where I should have power and when on the glow plug relay, but I can't find it. Does anyone have a copy that can post for me? I think my relay is going out. My truck is hard to start when it's cold, and I have smoke coming out of the tail pipe when it's cranking. When the engine is warm it fires right up. I've replaced the glow plugs with OE ones recently when I did my valve covers, so that it why I think I have a relay problem.
Thanks
Tim
