Maybe you screwed up and wired something into the fuel tank pressure sensor? the multiple high voltage codes you have would re enforce my believe that somehow you have screwed up the 5v ref. and the timing of it too.

Okay I'll be reading through the FSM today to gather as much info as I can and see if the two circuits have any common route. Both my codes are high input codes. I honestly think I know what is causing those codes though. When I depressurized the fuel lines I didn't unplug the fuse. I just unplugged the fuel pump and cranked the car. Yeah obviously that will throw a Cel and I knew that from the beggining, I just figured it doesn't matter and it'll be fine once I clear the codes. I bet that has something to do with the short or wiring issue. So basically, to test for the 5v reference I can use my multimeter at certain sensors and test for the 5v power supply?
