Today the pump did cycle and it started but ran for about 8 seconds before dying. Then, as before, no more sound from the pump and she would not restart.

Pressing the reset switch did not help. I managed to remove the black plastic cover which is partially silicon-sealed to the fuel tubes, and verified the unit shows BMW markings. I did not test the power leads but will do so tomorrow.

86mog, did they replace the entire assembly or just the pump that is part of it? You wouldn't happen to have a part number?
