Chevy Lumina not turning over at times?

Thanks for the info. It's not the original battery and I don't have any anti-theft system on it but I will check the voltage on the starter at the purple wire next time it happens

Thanks again

If it the original battery in the car from the factory they were bad for internal bad connections on the battery ...
You don`t have any anti theft lights on do ya >?
There was also a problem with the key cylinders having a loose wire for the theft system sometimes having a code stored ...
Will almost have to duplicate problem and check to see if voltage is @ starter on purple wire when it happens ect.
