1997 - No Start - Power comes and goes

Hi,

I have a 1997 Z-24 with an automatic transmission. For the past several weeks, I have been having problems starting the car. When I turn the key in the ignition, the dashlights come on, but nothing happens. No turn over. Sometimes if I hold it there for a minute, it turns over and starts fine. I noticed when this happens, the radio clock always resets itself to 1:00. The other oddity I've noticed is that sometimes when I hit a bump while driving, the parking brake and ABS lamps will light up and won't turn off until I turn the car off and restart it. At first I though it was a bad battery cable...it was frayed so I had it replaced...thought I had the problem nicked, but it's still happening. This morning while driving to work the car stalled at a light when I turned the A/C on as if the drain on the electrical system killed it. It didn't want to start (same thing, no turn over etc.) but eventually I got it going and all was fine. It seems to be worse when the car has sat all night or if it is damp or raining. I have read through other posts that some people have heard clicking and buzzing noises under the dash, which I too have heard when it's acting up. Any thoughts would be appreciated. I hate to put it in the shop and spend a fortune having the problem diagnosed through trial and error if someone has a good idea what's going on. THANKS!!!

I finally took it to my garage with a detailed description of everything that's been going on......diagnosis.....bad NEGATIVE battery cable. Corroded and loose.

They serviced it, checked the alternator and and tested my battery and all showed good.

It's only been 3 days since I got the car back, but so far so good!

Wish me luck!
