I have a 1991 Mercedes 190E (gasoline, not diesel), and while it's still a reliable car, it has a strange problem with starting the engine that left most people I asked puzzled (including mechanics), so I'm posting the situation here hoping that someone might have experienced something similar.
If I try to start the engine after not using the car for at least a day, or if I start it up within a few minutes of stopping it (e.g. dropping a friend off or waiting for a train to pass), it's all fine.
However, if I try to start it within a a few hours (but less than a day) of stopping it (typical scenario: leaving it in a parking lot when going shopping, to the cinema etc.), I hear the starter "buzzing" and all, but the engine fails to start up. It usually takes many-many tries, to actually get it started. I've found that it helps if I step on the accelerator pedal while turning the ignition key, but even then it takes a few minutes (and a few key-turns) to get it running. While it never actually left me in the parking lot, I'm very afraid of this scenario so I'm using it less and less for shopping. I've tried taking it to a mechanic of course, but they haven't found anything.
It might be worth noting that while the battery has been replaced quite recently, so it should be reliable, we routinely use a nonstandard "master switch" to cut the car's circuit from it, to make sure it doesn't drain unexpectedly. I don't know if this is relevant to the issue.
I suspect a bad check valve is allowing the pressure and "head" of the fuel tank to bleed off, requiring a lot of substantial fuel pump work to get the air out, eliminate cavitation at the pump, and reestablish sufficient fuel pressure.
Try cycling the key on and off a dozen times, without actually turning to the "start" position. Just ignition on, wait ten seconds, off, ignition on, wait ten seconds, repeat. Then attempt a normal start.
Also, before starting, if you hold the accelerator to the floor, this probably initiates a "flood clear" mode. This prevents injection, but allows time for the fuel pressure to build. After a few cranking tries, no more than 10 seconds long each, attempt to start normally.
The fuel check valve is screwed into the fuel pump body on the underside of the vehicle, I believe. It's an inexpensive part ($20 ?) if you don't get the OEM one from a dealer - which is probably a few thousand Deutschmarks...
Another possibility is a bad fuel pressure regulator, which has a ruptured diaphragm. This allows fuel to leak into the vacuum control line over time, creating a flood condition. If the first test I suggested is unsuccessful, try the second test. If that works, you are clearing a flood condition and the fuel pressure regulator is more likely the culprit. You could also simply disconnect the vacuum line at the fuel pressure regulator and see if there is any liquid gasoline. There should be NONE. It might smell like gasoline, but there should be no visible liquid.
These are simple DIY tests you can perform in your driveway. The professional route would be to connect a fuel pressure gauge and observe the readings while starting, as well as after turning the engine off. But not many of us have access to a good [expensive] fuel pressure test set with all the adapters, especially Euro/German...

Sometimes I don't actually hold the accelerator but "pump" it with my foot. After a few tries, the buzzing turns into audible (but weak) cranking, and after even more tries, the engine starts normally. At that point, be sure to keep the accelerator pressed (if you let it go it will die again), then let go of the clutch and get going. If you drive for a few minutes, it usually gets into a stable state.
It never had a problem starting before, always started in seconds, and one day suddenly it won't start. This was April, and the previous time the vehicle was driven was December. So I try to start it in April, with the battery freshly charged, and it won't start, the starter is turning the engine like crazy, the engine makes sounds like it'd almost start, and then it doesn't. After many times trying to start, turning the engine with the starter for probably something like 5 minutes in total or more (this only works if the battery is fully freshly charged), it finally started, and once started it run fine without any issues.
