I went to start my 92 lumina and it wouldn't start... the battery was dead, so I jumped it with a jump box and it was fine... I drove it to the store and back. 2 days later the battery was dead again so I tried to jump it and it wouldn't jump so I bought a new battery installed it and it worked fine. 3 days later, it would not start again! The battery is not getting charged! what should I do??

First you half to determine if the alternater is working. you do his by jumping the car and while its running take of the neg cable off to the car if it dies then you know the alternater is not working properly,
if it stays running you know you have a electricalen short you half to trace down

This procedure usually works:
·Check the battery cable connections:
Make sure the negative cable makes a good ground connection at the battery and (preferably) at the engine. Make sure the positive cable, makes a good connection at the battery and at the starter.

·Check the battery the simple way, like this:
Turn on the headlights, then try to start the car.If the headlights do not dim or go out, then the battery is likely ok.

·Check the starter and solenoid:
If the wiring looks ok, then look at the starter solenoid for a good connection, and proper voltage at the starter(10 volts minimum while cranking).
If the starter spins and no crank, the problem is most likely the Solenoid's pinion gear is stuck.
Have someone hit (not too hard) the starter while you try to start the car. This usually works by dislodging a stuck pinion gear.
·Make a simple test of the alternator:
If you can, somehow get the engine running, measure the voltage at the battery. It should be at least 13.6 volts to properly charge the battery.
