Question about 2001 Pontiac Bonneville
I would have suspected the ignition switch, but it sounds like you've replaced it. It is internal to the housing you described. The first thing to do is to actually check for power at the ignition switch. There are 2 connectors going to it. One provides power, the other sends out power when key is turned. Check for good 12V at both the larger red wires, they should be battery powered and live all the time. If you have power on them then turn the key to run, you should have power on the orange wires (ignition feeds). The large yellow wire should only have power when key is in crank position. If there is not 12V at the red wires all the time then likely you have a large (maxi fuse 60A) under the hood electrical center blown. It could also be a blown fusible link coming off the starter battery post that feeds the electrical center if the fuses are good but no power across them.
