i have a 97 lt1 that starts up everytime with no problem except for a few times where it seems that the car has no power radio wont turn on/ car wont crank but the car will fire right up with a jump start. any ideas?

 

Check current draw with a multimeter with the car off. Check for corroed cables.

 

I have the same problem. I got a battery, alternator test and everything was good but the car was still loosing juice. I tried the multimeter but did not have the instruction booklet which would have helped. I got a new battery and for now, it fixed my problem. Might try that, if the multi-meter idea comes up short

 

wow this just happened to me 45 minutes ago, i just jumped it and it works fine now.
