I am having a problem with my 85 190 2.3 that has been going on for several months now. In the morning it is semi-difficult to start. Once started it runs very rough till things warm up. Then it runs great. If it is run for a while and then shut off for say 30-40 mins, its very difficult to start. Sometimes taking 3 trys with 10-12 seconds cranking. Fuel filter and pump are new. FPR can be eliminated. I was told by one mechanic to replace the fuel accumulator, but when i was going to order it, the salesperson said not to waste the money on the accumulator, that leaky injectors are a more likely culprit especially if the car has more than 100Kmi. Mine has 165Kmi. Does this sound right? I do have the service CD, and plan on buying the pressure gauge set, but if i can repair it myself sooner i would like too. Thanks so much in advance for any advise.

I would have to agree with your mechanic. I and others on this forum have replaced things like the fuel check valve, accumulator, filter, plugs, rotor and cap partially in pursuit of solving this problem and I am narrowing it down to the leak down.
You might want to check your Overload voltage relay as well before doing anything.
Also do a search on this forum for 'warm hard start' or 'hard start' some good advice from Benzmac and other techs here.

Yal,
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?

Thanks,
Paul

Paul I still have the problem. So far no cigar! My next cheap change will be the coolant sensor. The reason I am throwing money at this is I can live with the problem and its kind of like getting to know your car times for me. I can't remember the thread but somebody here changed the injectors and problem was solved...I am working my way in that direction also...i'll keep you posted.
