corvette won't start,even after jumping, and noise if take out key

Wow- that is a really nice car- and very sophisticated, mechanically- don't be messin' around under the hood- you'll just make more problems- put it on a flatbed tow truck and take it to your Chevy dealer for repairs or to a really good garage that works on classic and exotic cars- and my answer would be the same to the guys

Thanks. Called a couple of members from my club they bought agreed with you. I asked a third party and said to buy a new battery and if didn't work than put in the old one and call my car dealership. So I bought one and he put it in and couldn't believe it, turned the key and music to my ears that beautiful sound. $$$$ was in my mind all day never thought one dead battery could make all that sound. Thanks again for your suggestion though.
