Help!

I have an '82 300SD. It will only start with a shot of starting fluid. Smokes like a smoke bomb for about a minute then runs fine. It will restart while it is still hot. Once the engine is cold, you can crank it till the battery dies and it wont start. I have replaced the alternator, battery and fuel filters. No change. ok gurus........whats goin on here?

What about the glow plugs? When were they last replaced? If its been a while chances are some if not all of them are bad. Go at them with a volt meter to see if they are getting juice. If they are go ahead and check their resistance. A search will tell you how to do all of this.

If the glow plugs are OK, then the next thing I would check is the compression. It should be one or the other.

IF the glow plugs are working fine, then it sounds like low compression. However how did you determine the glow plugs are fine?

First of all my mechanical abilities are zilch..... I'm an electronics guy. The glow plugs were checked on a volt/ohm meter. I foget what the number was but they were declared ok. This problem began about a month ago when I ran out of fuel due to a faulty fuel gauge.

So the problem started suddenly?

Well then it isn't mechanical. It really sounds like bad glow plugs.

I dont know if it matters. but it takes quite a while for the glow plug light to go out.....at least a minute. Been like that since the last time they were changed.....(about two years ago)
