I have a 1987 300E, and having starting problems, and i replaced many parts also, but it did not help.
I have seen many of you writing about fuel relays,ovp,etc., which is connected with bad fuel distribution.
In mine case it.s a rich fuel delivery, it's sending to much fuel!
Engine is full of fuel, fuel pump is working but having high pressure.
I replaced fuel regulator, and fuel distributor, but did not helped.
Is it steel in connection with f.relay and ovp?
What about fuel sender?
I checked every topic on this forum, but none is related to my problem.
Thank you in advance!
