Make sure the Red wire on back of the alternator has 12volts to it (red single heavy gauge wire).On the battery most GM cars/trucks have

2 positive cables on the battery make sure that they are free of acid build up and are tight.

This doesn't sound like a computer issue to me. Is it possible that something (trunk light, glove compartment light, etc.) is draining your battery when the car is sitting? Are the main battery connections clean and tight? No damage on the cables? Solid ground connection on the engine or body? Do you see any activity from the "charge" indicator on the dash? The starter is also a possible suspect.

sorry you have this problem first i would check battery voltage before and after you start you should have 13.0 to 14.2 is the battery light on? do you have power at the large red wire at the back of alt. if you don't have power at the bolted on wire on the back of alt. thats were the fusable links or the maxi fuses are the problem pull the fusable links at the starter to check
