I just realized the end half of the post is black. Copied it over from WORD. The last paragraph is below:
The truck runs great, but starts rough in the mornings. I let the glow plugs go for about 5-7 seconds, then crank it. It fires right up, but then either dies or runs very rough. It sounds like maybe there’s a cylinder or two not firing, and there’s plenty of white smoke coming from the exhaust. Once warmed up, it idles perfectly with no smoke.
I know it’s an old diesel, but it seems like it should be starting easier in 70 degree weather. Could it be an injector timing issue?
