Citroen Ds injection problem

Little update this morning I checked with the list Norbert shared in the last post. There was a bad connection from the map sensor. Fixed this and the engine was running again.

With the spare ecu the fuel pump stays on for 2 seconds and the engine runs fine. Changed again for the original ecu and the symptoms are right back, bad acceleration and fuel pump runs always with ignition on.

I can concluded the ecu is bad, opened it and seeing a lot of oxidation on different parts of the print.

Thanks for the help
