My 2003 chevy cavalier decided to completely loose power overnight. Nothing turns on

[JSP]

w/the key in the ignition? Its not the battery, there is no clicking noise, unless its extremely dead. No lights turn, no guage movement, absolutely zero power. I already replaced the fuel pump a couple months ago, so i know its not that. Always done regular oil changes. Any suggestions? Car has about 110K miles..

It has almost positively got to be a dead battery. The only other thing I would check would be the ECM. electronic computer module. good luck! let me know when you get it fixed ok?
