My fuel pump makes alot of noise. Is that I sign that it isn't pumping enough gas to the injectors? My car wont accelerate without studdering.

What kind of noise does it make? Do you only hear the noise at certain times? Does the noise have any variation or is it constant?

The sound is a consistant low freaquency vibration. I think it's just getting loud from ware. I'm looking for the reason my car is ideling fine but can't accelerate. From the symtoms it should have been the fuel filter but I changed it, the plugs wires.

How many miles are on your Mustang? I doubt there is a problem with your fuel pump because many of them are noticeable when turned on. My fuel pump is LOUD but that's the way it's supposed to be. How old are your spark plugs? Are they set to the proper gap? Also, you should double check your ignition timing because if it's off, your engine will shudder during acceleration.
