See if this posts...So thanks for the comments esp nuts 4 benz...The issue was mysterious BC all fuel pumps were working and relays, FP relay and OVP as well..PUmps humming.

I found if I unpowered the rear FP, first at the tank..the car ran! I removed the pump and cleaned everything and on reassy found that it all worked perfectly...My belief is that the flakes from the fuel tank formed a plug in the check valve which under pressure blocked the line..depowering the pump allowed fuel to be drawn by the forward pump..

I replaced the fuel filter and cleaned both check valves and ...

hopefully this will appear..and Eurosport?? Just here to post useful info..I had no useful infor in the first three comments..nothing personal..and one cares little to be quoted OEM and then offered a great deal..All Mercedes DIY people know that game too well..not that a good parts source isnt valuable but...we dont need to come here to learn what OEM prices are! (actually my dealer will give me a DIY rate on parts which is very reasonable and steeply discounted)
