no the car want start, the battery is dead all the way

Answer to PM: you have a parasitic drain, Get an analog voltmeter remove the negative battery cable, attach the Black lead to the battery post, Red lead to cable end, then pull fuses one at a time, make sure there are no accessories or lights in the on position, Key off! Close the door after each fuse and check meter, when you pull the fuse for the bad curcuit, the meter will drop to 1 volt or so. Check all fuses, even under the hood. If meter does not drop, remove the battery connection from the alternator, if it drops now, the diodes are bad in the alternator. Put the fuse back in were it goes as you go so you don't forget which fuse goes were! Mind you GM with onstar are tough to test, it's a matter of waiting for stuff to cycle off, Might want help on this one!

Why was an alt and starter put in? How often is the car driven? How far? What kinda parts did you buy?( Where from?)
