Hello and thanks for your great teachings! I have a 560SL from 87 US model, federal (not California). The engine starts well and idles well too. The problem is it cuts out suddenly, particularly when going up hill but also happing on flat areas too. Restarts again with a few cranks. Replaced the pumps, filter, accumulator, EHA (adjusted the screw), potentiometer (adjusted to 0.7V), O2 sensor as well, but didn’t fix. Do you think is the pressure regulator? That’s the only thing missing… the X11 shows close to 100% which makes me think this car does not have the codes coming out… or maybe is just too rich…
Thanks for your comments. I looked already into all your videos… my situation is different as I don’t have idle problems or rough running engine. It looks to me the internal pressure of the fuel distributor gets way out and then either the ECU cuts off the ignition or the fuel does not flow to the injectors. There’s not much info about the pressure regulator, but it looks like is in parallel with the EHA (=EHS). Above a certain pressure should open to the return line. So as the engine load changes when pressing the gas, the fuel pressure increases and the fuel regulator should put it back to the nominal 6bar. Maybe you have a different understanding of this.

Hello,
I would check the EHS, idle speed actuator, ignition system, KPR and idle speed control relay.
Look in the playlist English videos
Best regards

Problem found… steadying bowl inside the tank full of junk, blocking the flow to the pumps.
