I recently purhased a 1981 300D. The car had started easily everytime until yesterday. I noticed that when the key was turned to the NO II position that the glow light was not coming on. This morning I tried to turn the engine numerous times but it would not turn over although the exhaust did emit quite a bit of smoke. Finally I ended up taking my wife's car to work. Any suggestions? I've read other threads regarding glow plugs and it sounds like the same issue.

Thanks
