the glowplug light on my `91 350SDL now comes on immediately after the engine fires up, but not before....(the glowplug system had functioned properly) i thought i read somewhere that this is diagnostic of an open circuit in a plug. i know one of my plugs is kaput; just wondering if anyone had heard this?

Yes you are correct. Change the glowplug(s) and your light will act nortmal again.
