no power at all

[quote:fdc6942b16="seokid"]hi, my sister owns a 2000 ford escort w/ close to 100,000 miles. the problem is that at the current moment the car doesn't run after having sat for a week. there is no power at all. the car wont turn over and there is no power at all in the cabin. we have bought a new battery thinking that the other one could be dead, but that hasn't helped. could this be a fuse or ground wire?[/quote:fdc6942b16]

You need to check all your fusible links some of them could be in the power distribution box and starter relay, and also could be at the starter-it has to go thru the links before it goes inside the cabin.
