Default 2002 pt cruiser electrical issues

lets start with the story about the car

I bought it on a ins auction the key in it was no a transponder

I took it to my local dealer they cut a key and when they go to program it their scan tool does not see any computers on board so I dont have a transponder key programed the battery is not dead

checked fuses and power dist box out front all look good

this is what it will do
heater fan
brake lights
door chime

can any one tell me how to check and see if my computer is getting voltage or is there a lockout that they dont know about

any help would be a great help

thanks Dennis

You have no idea what that car went through before it went to auction. My guess is that it's one of the thousands of cars that were under water because of the last big storm on the east coast. Now's a really bad time to pick up a used car, especially from an auction because of all the cars damaged by the storm. Your computer could have been underwater and completely shorted out. If the dealers tools don't recognize any computer at all, that's where your gonna have to start, by replacing it, then go from there.

Try this link; it is a 2002 wiring schematic. Not sure how complete it is, as it differs in style from the 2003 and 2004 diagrams that I have.
