Bad alternator, bad alternator connection, bad ecm. Those are the most common causes. That code only comes on when the engine rpm is over 800rpm though. Double check your ecm connection. Try and turn the car over with the alternator unplugged! Watch the voltage at the battery very closely! Then when you've tried all that come back and make a post and I'll post the way to check the voltage at the ecm.

ok well i went back up to work where the car was dead with the spare key that i so luckily have and it started thanks *** .my buddy suggested that i use the other key after i searched the boards for code 53 and saw that some people mentioned it could be the vats system at large in a few of those code 53 posts.and then when i got home,i used the key that wouldnt work for $hits and giggles,and it worked.i dont know whats going on.i dont really care though as long as my car works.i think im going to bypass the VATS so i dont have to worry about it screwing me over again.thanks for the post anyways JPrevost.
