1993 300SD Cranks, won't start & Glow Plug Lamp I

Hey Anyone,

I have a 1993 MB 300SD that was given to me as a gift, and I love it! It has a few issues though, like not starting right now:

1) I tried to start it today, it cranks (until I killed battery), but won't start.
- saw smoke from tailpipe, and it acted like it wanted to start but wouldn't.
- It was cold and rainy today (47 F)

Any suggestions?

2) I have noticed that since I have owned the car when I turn key all the way glow plug lamp does not come on until 30 seconds or so after it is running.

I usually wait for glow plug lamp to go out and then drive it.

Does this sound like glow plugs, or glow plug lamp relay.

Has anyone had similar problem?

I appreciate any help anyone can offer.

Start by checking the resistance of the glow plugs. Good ones will read about 0.7 ohms. Replace any bad ones. If your battery is more than about five years old, I'd replace it too since you have drained it at least once. Probably could use a valve adjustment too.
