Unhappy Warm Start Difficulty - 1992 300E

My 1992 300E is having problems starting when the engine is warm. Cranks fine, but doesn't 'ignite'. Is this an accumulator problem or a pressure leak in the fuel system... why the problem only when the engine is warm?

Do a search. Lots of posts spanning many years.

It could also be leaky injectors.

My best guess is that it would be the accumulator,check it by crimping the fuel line (small) now remove it,place a bucket under it,you will have residual fuel run out,then stop,run the engine shut down several times if at any time fuel runs out of the accumulator,REPLACE IT.I assume you have done all the fuel mixture settings lamda is correct?o2 is good?x11 is at the propper percentage? JNT.
