Newbie here. First post. I have a 99 Sunfire, 2.4 w AT/ loaded. I just changed the ignition switch and followed all the instructions concerning this. After Anti-theft reset, the car ran great. But... In putting back the plastic steering covers, I unhooked the ignition switch and removed thinking the Hat went outside the cover. In removing the switch, I forgot to unhook the battery. After plugging back the switch electronics, the car chimed for a few seconds and the electrical system went dead. Visually checked all the main fuses still no power. At a loss on what I could have done to it. Does anybody have any knowledge on this issue on what to do and possible problem?
