My 96 monte carlo won't start i have a new

start the car then remove the negative battery cable if the car still runs them your alternator is working properly and you need a battery. I have also gotten bad rebuilt alternators from on several occasions for this type of car and had to put on new AC delco ones but they are a little more expensive.

bad cables or something with corrosion on it or just a bad battery-bad ground, alternator going out could be a lot or just something minor

Could be a bad battery, and or alternator, if the alternator does not charge the battery when the vehicle is running your battery will drain causing no start.

Hi Carl, When it shuts down do the ignition and warning lights come onto the dash or is the dash blacked out? What has caused you to think its the alternator and battery? When it cuts, does it start right up again, or do you have a problem to get the starter motor to turn the engine? Have you checked the battery connections. Have you checked anything else for faulty connections? Regards John

Possible Problems 1. Battery dead (if the horn does not blow then that's what it is) 2. Alternator is malfunctioning (the thingy that makes the sound when you turn the key in the ignition)

sounds like a dead battery

Check your ground cables. All the ground cables you can find. Most of the time there the black ones. Remove them one at a time and with a wire brush, clean them off. clean them really good then put it back on tightly. Mainly the one that goes from your battery to the engine block. i had the same problem.

check fuel pump quick check spray starter fluid if starts no fuel reaching throttle body if no start or gas is present at throttle body check for spark from distributor to coil pack

check to see if the wire is broken for the passlock/passkey system in the ignition lock cylinder, its common for the copper wire to seperate inside the insulation, when you tilt the column it could have been pushing the wires together enough to touch inside the insulation

if you remove the battery and charge it than reinstall (make shore all lighting and non essentals are off) and if the car runs for awhile then the problem most likely is with the alternator
