The car runs great when first started, great pickup, etc. However, if I stop and shut off the engine, it will not start back up. At times I can pump the accelerator 5 or 6 times and then it will start if I keep my foot off the pedal, but not always. Any suggestions?

The glow plugs are good, I've recently adjusted the valves, filters all replaced, linkages replaced, turbo working properly. The first symptom was the car having no power or losing power on hills, but that is no longer the problem with the mentioned fixes. Just over 200K on the odometer. Another recent change is that I'm not driving the vehicle as much.

I presume by not start you mean the engine turns but never fires? And TD - Turbo Diesel? –  Dan Jan 25 '13 at 14:08

300TD is the model number of the N/A diesel station wagon. Clarification would be useful. –  Timo Geusch Jan 25 '13 at 16:17
    
300D Turbo Diesel 4-door sedan - not the station wagon. Yes, engine turns but will not fire. –  user2680 Jan 27 '13 at 16:38

Sounds like a lack of fuel getting to the engine.

Get it hot, turn it off pull a fuel line and crank the engine, see if any diesel comes out. It could be a fuel line softening up when it gets warm and pinching shut due to the suction from the pump. If thats the case, replace your fuel lines with proper diesel rated lines.

Another easier thing you can check, is when it wont start, open the gas cap, if there is a woosh of incoming air and then the car starts, your tank is not venting and is probably a bad cap. ($10) –  Matt Bear Jan 31 '13 at 22:11
