2000. Why do the battery and ABS lights come on suddenly?

SOURCE: Grand Prix wont start

Try checking the starter solenoid wires.Make sure the wire hasnt come loose and the battery to solenoid cable is tight.

SOURCE: ABS messed up

abs relay
change it before your breaks dont work at all

SOURCE: all of a sudden wont go forward or rev .

Hello, The first thing to check is the transmission fluid level. When you check the fluid does it have a burnt smell? If so, you probably have an internal failure. Have you had the transmission serviced? Your trans filter may be stopped up.
I hope this helps.

SOURCE: Battery and ABS light coming on

There is a part on the engine called the "Alternator", the alternator is what charges up the battery and supplies the power to the cars electrical system when the engine is running, when the voltage output of the Alternator is to low it causes the Battery warning light in the dash display to come on (to alert you of a problem in the charging system), the low voltage from the alternator also is what is causing the ABS warning to come most likely. So at this point you will need some basic testing done to determine the cause of the low voltage, this can be the alternator is defective (most likely reason) or other things like wiring issues to the alternator.
