Question on Fuel Pump and Filter Replacement

Hello, I have a 2003 Cooper S and came back from a business trip where the car was in a parking lot for 4 days with lots of rain. Started the car as usual and it ran for about 10 seconds then stopped. Tried starting again and it would not turnover. Tried starting the next day same thing, ran a few seconds and stopped and could not start again. A towing company came to pick it up but the driver tried a few things first and what he tried last was he had the key turned in the ignition and he got under the back of the car and hammered around the gas tank then told me to get in and start the car...it revved right up! Really nice of him to help and not get charged for a costly tow! Drove home fine and days later same thing again and now I have hammered it and it starts right up. This loosens sediment in the line so it can get gas? Does this mean I need a new fuel pump? What might something like this cost? Single income with no extra cash flow....bummer : Thank you for all your help!!

Sounds like a faulty fuel pump. I would perform a fuel delivery system test. Check fuel pressure, volume and quality.
