Im lookin at a early 99 7.3 and i cant find any real answers on this. When i went to look at it and started it on a cold motor (70* out) it fired right up but put out quite a bit of white diesel smelling smoke for probably 2 or 3 min. After that the smoke went away and it ran awesome. Also while it was smoking the a/f guage was reading really rich. It has exhaust intake and some sort of one setting chip not sure what kind. I really like the truck but ive heard white smoke at start up can mean injectors, but some people have told me its normal to. anybody have any input?
Ya i did some more research and now im almost positive its glow plugs, i watched some vids on youtube and this one smoked even more so im thinkin maybe the glow plug relay is bad causing none of the glow plugs to be functioning. As for the air fuel guage i have no idea it was in the cab but i never saw it move so im not sure on that one i hadnt ever heard of that in a diesel either but im thinkin it had to be non functional. If its just glow plugs that doesnt concern me to much at all ill just go ahead and replace them all plus the relay.
