My 1977 240D died need help!!!!

My 1977 240D standard was running great and always has until now. I came home and there was stuff in the driveway so I parked in the road and turned it off so I could move everything in the driveway. I went back 5 minutes later to pull it in and the car is dead when you turn the key to start it. The glow plug lights up on the instrument panel and I have power but when the light goes off and I turn the key to start NOTHING. what the heck happened? All the connections to the starter look good and there has never been an indication that the starter had a problem. Anyone have an idea whee to start?
Thanks
Bev

It doesn't matter if it is in gear or neutral, I get nothing when I turn the key.

Pull off your battery cables and clean them and your battery terminals with a wire brush and some Coca-Cola (or off brand Cola) until they are nice and shiny. Put them back together and try to fire the car up. If that doesn't work, see if you can get a jump start or push start (have someone push the car while you are in second gear, when you get up to about 10 MPH, pop the clutch and it should crank assuming its warm)

Sounds like you MAY have a bad cell or 2 in your battery, if you can get it started drive it to an Advance Auto or Autozone, they can test (FOR FREE) your charging system and battery for you and tell you what you need to do.

DO NOT SHUT THE CAR OFF when you get there. Being a diesel it will stay running with a dead battery however, you're going to need it running for them to run the charging system test.

I get power to glow plug, lights, radio and 12V to the battery, I tried to place a screw driver between the selenoid and the starter to see if the starter would turn over but nothing. Seem to get 12V to the relays. Still nothing when I turn the key to start

Ok the battery is putting out 12V but when you turn the key to RUN does it drop or stay the same?

This happened to me about 2 weeks ago and cleaning the battery terminals did it for me. But it may not be in your case. Can you try jumping 12v directly to the starter?

If you put a wire directly from the battery to the solenoid, and it doesn't start...I would say the issue would be with the starter. Your ground cables may also be an issue, the transmission to the chassis and the battery to the chassis are the main grounds. You can also attempt to smack the starter with a hammer to get it to go again...

That happend to Me. The Engine started fine when I left to go to a Realatives House. Started when I left the House.
I stopped to get something to eat and went to start and got nothing.

I had Multimeter in the Car and the Battery has 12 Volts.

I got a piece of Wire to Juper the Starter at the Solenoid and it only produced a tiny spark. I tried the Wire over the Battery Terminals and still only a tiny Spark.

I figured the Battery had some internal damages and walked a crossed the Street and bought another Battery.
With the new Battery the Engine started normally.
