Thank You Norbert.
I have - as I wrote above - cleaned the tank and replaced all filters, and I have isolated the problem to fuel pressure. The question is how remedy that issue

Hi Chris,
all you do is put a fuel hose on your pressure regulator exit to tank and measure the delivery rate into a bucket. But you shall see 2 bar in fuel line before regulator and engine shall not run. Just attach ground to pin 19 of ECU. It will trigger FPR (Fuel Pump Relay).

Hi Chris,
I was triggered by the rebuilt fuel pump.... Mayba a good idea to check the pressure direktly from the pump. I I am correct, should be approx 3 bar
kind regards
Heinrich

Hi Heinrich
that is not good enough. Ultimately you need to know how much fuel is delivered against 2 bar pressure regulator. If that value is too low, you will see that pressure will drop during higher consumption.

Thank you Heinrich, when I restrain the outlet line from the Fuel pressure regulator with a pair of pliers the pressure rises immediately to above 4 bar, However I do not want to break anything - so I have not tried the max pressure, or if the internal over pressure relief valve in the fuel pump actually works.
Best regards Chris

Hi Volker,
got it however in case Chris got a pressure of 4 bar immediately, maybe a bit more, do you think it is the correct fuel pump for a D-jet system ? I have in mind approx. 3 bar and a bit in original configuration (for MB)
Anyway, then, must be something wrong with the pressure regulation valve...
