I just got my mercedes this month. It's a 1985 300TD. I had trouble starting it the first time, and have had no such trouble again until today. It was in the teens F this morning and I tried starting a few times, doing what the manual told me about pressing the pedal and I have had no luck. I tried warming the glow plugs a few times and starting afterwards but that didn't seem to help either.

I'd like to know if I have damaged my car. I've been going out once every hour to try to start it and still have had no luck and I think it is in the 20s outside now.

I don't know anything much about diesels and was told that this would be a good resource to try to figure things out.

I don't have anywhere to plug the car in. Any suggestions on what to do now?
