$400 Find, Vacuum pump seized? (see pg 5)
Edit: now the engine seems to have seized. Any help would be greatly appreciated. See Page 5.
Just got a second '79 240D with 300K on the clock. The car is a stick and has no rust on the body, and a manual sunroof. The vacuum locks still worked after sitting for weeks. The previous owner said it lost power and died on him on the freeway. I tried swapping the fuel filters and bypassing the fuel tank using a small bottle as a temporary fuel tank, but it won't quite fire. It has the old style primer pump, but when I prime it the clear pre-filter will never get more than half full of diesel. The emergency cut off looks to be in the depressed position. (see picture below)I'm not sure if that has anything to do with the non-starting or not. The only other problem is the clutch squirts fluid when you press it. It looks like the flexible line between the master and slave cylinders has a leak. I plan to check the lift pump tomorrow, and maybe try a tow start. Anybody have any other ideas to try to get it running? Thanks. –Bryan Edit: it is a 240, not a 340.

Whats up with those screen door style springs on the linkage....something just looks wrong there.....
I'll bet its not starting from a fuel problem. Rarely do these cars just go from running fine to "lost power on freeway and died" sounds definatley fuel related. If compression is in question, perform a compression test and that will reveal the state of engine health. Good luck! I hope you get it running!

Second. Are all the glowplugs working? Third. Sounds like the primer pump might be bad. You should be able to get the updated one for around $20. |

I don't know about the springs either. I disconnectend them and it seemed to spring back normally. I checked and the GPs seem fine.

disconnect a hard line or two from the injectors, crank, and see if they squirt any fuel, if not, there's the culprit. If they do I'd look further into the timing/glow/compression category

I would stick in the fast GPs, that usually helps, but a tow start does sound like a real good next shot. I had one that took about a mile of towing to get it started but then she always fired right up so give it a good long tow. If she wont start I would check the compression, even cold it might give a clue.

I wouldn't spend any money on it until it runs. Tow start it and see what happens.

Eventually I'll upgrade the plugs, but the loop plugs seem to be working for now. The accelerator linkage seems a bit wacky. If you press the stop button, it can not depress. From my memory the linkage seems to move less than my other 240, but I can not directly compare them because my other Mercedes is on the other side of the state. The rod that runs to the injector pump has a max travel of 1 inch or so. Can somebody compare that to their car and let me know if it is close?
Is there any chance that the lift pump, or drive for the Injection pump could have failed? Thanks. –Bryan

Try cranking with the linkage/pedal at WOT.

I'll take a look and a picture of that area tomorrow. I haven't spent too much time looking in that area on my working car so I'm not sure if I will be able to tell if it doesn't look right on this car. Maybe you can look at the picture and see if anything looks amiss. Thank you.

Your linkage definately looks wrong with those springs. But cranking it at WOT, as others say, should get it at least some fuel I would think.
