alright, well the car isn't an f-body but it is a GM v6 and we're having some trouble with it. My friend and I were swapping dashes on his 97' Chevy Lumina LTZ, the reason we were doing this is because we scored black leather seats from a monte-carlo for a 100 bux, great steal but the luminas interior was still light gray and the dark gray would work much better with the leather. So we went back and pulled the dash from the monte to go in the lumina, after believing we had all wires hooked up properly and the dash re-essembled the way it should have been done we tried to start the car only to find that it has no response. The battery is reading full, and according to an OBDII scanner the car is losing power while the key is engaged, yet the starter doesn't click over. Does anyone have a clue as to what in the electrical system would cause something stupid like this to happen? it's being a bit of a pain trying to figure out, and continuouly retrace wires, we do however have the original dash and all electrical components , would it help to switch all the original components onto the new dash to ensure proper working order?

thanks in advance
