1997 le sabre nothing on key, no power, no radio, cleaned terminals and changed battery but nothing

Check the fuse links, if all ok, check the ground. If you have a meter, check for voltage from the battery all the way to the fuse panels.

I had this happen to my 97. There is a ground stud on the fender well by the battery. On mine this was corroded to the point that the car stalled. Before stalling my lights dimed when I used the power locks and my tranny wouldn't shift on it's own some of the time. Check out this ground stud, clean it up and see if it helps. There are a few wires going to it.
