I just left a post on our problem (
zerothread?id=422192).
We had the noisy fuel pump issue which was resolved with the pump being replaced. The car has stalled twice, dead in the water and would not start at all. Had to get it towed to the dealer which at first they stated, "The car started right up, we can't find anything wrong".
I talked with the service rep and mentioned that the pump had already been replaced and that's when we noticed the "stalling". They were finally able to get it to stall out and the culprit was the fuel pump.
I'll have more specifics (part #'s, etc...) tomorrow and will post it then.
If your EX sputters, has limited acceleration (even at WOT), or just flat out dies on you... it's the fuel pump!
