Multpile fuel pump failures
A friend of mine has an 2002 Mini S with 50,000 miles on it. A few weeks back, the car just died and wouldn't restart. I tinkered with it enough to determine that the fuel pump was not running. Instead of a whine the pump just made a single "clunk" sound when the ignition was turned to the run position. It was getting power and the fuse and relay were fine. A shop then replaced the fuel pump (from BMW) and it ran for a day and then quit running again. BMW said to change the gas in the tank and reluctantly warranted the second pump. The car ran for about another day and apparently the pump has failed yet again as the car died and will not restart. The pump is making the "clunk" sound again as if it is seized up. The only difference between failures was that the last time it blew a fuse. So what would take out three different fuel pumps like this? I have read about the ethanol/gas mix issues but another friend has a Mini S and has no issues. I can't see bad gas killing a fuel pump in one day. Does anyone have any ideas? Thanks.
