Fuel Pump Driver Module P1233

I have an '01 GT thats been having problems when I hit 4500 rpms. The car sputters and bucks. I checked for trouble codes in my Diablo and found P1233, Fuel Pump Driver Module Disabled or off Line. I believe this regulates the fuel pump and just how much pressure it puts out depending on what driving condition is currently happening. Does anyone know where this part is, under the driver's seat maybe? Also, hopefully someone else who had this problem could give me some direction on how to correct it. Thanks

thanks, i just looked and i did see the box youre speaking of, i cant read a part# on it because the front is facing into the wheel well. have you had any dealings with this problem before?
