I just finished installing my new Accufab upper intake plenum/throttlebody combo on my 2000 GT and now my car wont even crank. before the installation i disconnected the negative on the battery and when i try to start it my theft light flashes. i have the factory anti-theft alarm, could somebody please please help i'm desperate to get it started before i have to go to work. and advice is greatly appreciated. I already tryed disconnecting the negative on the battery for 20 min. and that still didnt work.
