I did a search for hard starts. I noticed you had the same problem as i with your W124. Did you ever solve your problem? From what I can tell, the overvoltage relay controls the EHA, am I right? and from what i see the EHA seems to have other effects than what i have.... but i could be wrong. I am strongly suspecting a pressure leak somewhere, particularly the injectors. You said you replaced your accumulator and check valve to no avail, have you done anything with the injectors?

>>Also do a search on this forum for 'warm hard start' or 'hard start' some good advice from Benzmac and other techs here.
