Hot Start Problem
My Dad has a mint 1987 E 230. They use it as a second car, but it has recently developed a problem, and is difficult to start when hot. It's
spent a lot of time in the local garage, and they can't find a thing wrong with it. I'm not sure what they've done, as my
Dad's not too mechanically minded, but they've changed some "gaskets." The car runs like a dream, except for the starting
problem when hot.
Any of you have any clues on how to solve this?
Regards, Ian.

Is it fuel injected? If so, does it have the bosch L-jetronic injection. (the one with the electronic flap-type airflow meter)
If so, the non-return valve in the fuel flow damper near the fuel pump under the back of the car is probably knackered. No problem to be honest, just
gets vapour in the fuel lines which can expand due to the lack of backpressure. A few churns on the starter should clear it each time it happens.
Otherwise, you could try changing the damper but you'll have to find a goodun and they all seem to fail.

I Believe its Bosch KE Jetronic (Mechanical/Electronic fuel injection)
It may seem too obvious to check but worth looking at the distributor cap and rotor arm. A very common fault on the straight 6 version of this engine
is that it will start fine and run fine for exactly 20 mins then stall and wont restart. Dizzy cap and rotor arm fixes everytime???? Not so common on
the four cylinder but still worth checking given the time of year.
Not heard of the fuel vapour fault but sounds quite possible. In fact I probably have a fuel pressure valve if you wish to try one.
Let us know if you fix it or need more help.

Once had an old Volvo with this trouble , turned out it was the fuel pressure accumulator. As NS Dev says a one way valve in the fuel line that is
supposed to retain fuel pressure when engine is not running. May be worth getting a fuel pressure test done?
