Hi, I have a 1982 300SD Turbo and over the last 2 months The car has gotten harder to start. I bought a new battery 3 months ago.As of today I can not start the car and the battery will die in the process. I have a 300 1980 D and a few years ago I could not start car. $500. dollars later they replaced the screen in the fuel tank. On this car I changed the fuel filters and can see fuel in the line and in the primary filter. Any Ideas
Thanks

Glow Plugs and Injector Nozzles would be my advice. How many miles? Compression good?

Compression is that the dial that always goes to three when you give it gas ? the car has 173,000 and I added a small bottle of lucas diesel injector cleaner,with a little fuel in the tank then the next day filled up the tank.

I work on mostly OM615's, so I am definately not the best guy on here to be talking to you about your OM617, but here goes anyway.

Your glow plugs will be threaded into the engine on the drivers side (assuming LHD) just below the valve cover and just above the injection pump. There will be 5 of them in your car. I can't remember for sure but i think they have 27mm hex heads on them. Additionally they will be wired to one another in paralel with a short piece of wire that has terminal ends held to the end of the glow plug by a small nut. Remove the wires, remove the glow plugs and test them or have them tested for you.

Injector Nozzles are something else entirely and if you don't understand the Diesel fuel system on these cars and the basics of how a Diesel runs you should probably leave them to a tech who has training dealing with them and has the proper facilities for doing so. The need to be kept UBER clean, reassembled in the proper manner, and torqued to spec.

The gauge you speak of in the instrument cluster is oil pressure measured in bar. It does not indicate if you are getting appropriate compression in each of the cylinders.
