2003 Ford Taurus humming noise and wont restart

2003 Ford Taurus, mileage: 27,000. I could not start my car after just driving in it for five minutes. The car was making a humming noise but yet would want to turn over. A vibration and humming noise was coming from an electrical box that is located above the radiator above the firewall. This part was disabled and replaced immediately. The car started with no problem. I then shut off the car to restart it and it wouldn't start. The same noise and humming was coming from the same area after just replacing it with a new part. Something is burning out or shorting out this part and it has to do with the drive train control module. If you have any assistance or know of what may be doing this, I would greatly appreciate your help and the money you will save me by putting this in the shop without a clue.
