As if i needed more problems with my cars...
I parked the Bonneville less than a week ago, I've been driving the blazer. Yesterday i went to move the Bonneville, and the battery was completely dead. Which is weird because it only sat for like 5 days. So i got out the jumper pack, and tried to start it again. But it wouldn't start unless i gave it a little gas, but as soon as i took my foot off the gas it stalled out.
So i restarted it, and again i kept my foot on the gas for a few seconds let off, and stalled out again.
I did that a couple times, staying on the gas a little longer each time, but it kept stalling.
I figured I'd still be able to move it the couple feet i needed so i kept just enough gas to keep it running put it in reverse and went to put it back into drive, took my foot off the gas, and viola it stayed running.

Its done something similar before but not as bad, when i was driving it while the blazer was getting the rear-end replaced, everyonce and a while when i started it i would have to give it a little bit of gas for it to start, but it would stay running, and run fine after i let off the gas.

So yea I'm pretty confused, but i need to find out whats wrong because when i sell the blazer the Bonneville has to be my mode of transport until i find a new truck.

Sounds like maybe your alternator isn't putting out enough juice at idle to keep the car running AND charge your dead battery at the same time. The battery, until it acquires a little bit of charge, is probably drawing too much current from the alternator and taking away what the car needs in order to keep the fuel pump, and ignition coils going. If you hold your foot on the gas, the alternator ramps up the output and can sustain both the battery charging and the vehicle running.

As far as WHY your battery died, I'm not sure what to tell ya. Did you leave any lights on? How old is the battery?

No i left nothing on and the battery is new, not even 4 months old.

I'll have the alternator tested. Thanks!

Here is a way you can test some of your circuits and maybe find what is pulling your battery down. Take a fuse that fits in your fuseblock and grind the corners open to expose the connections to each leg of the fuse. Solder in some wires and an instrument panel bulb. Then, go through the fuse block with all accessories turned off. Replace each fuse with the test bulb. If there is current passing through the circuit, the bulb you placed in series will light. If it is in a circuit that should not have anything energized, then you have located the circuit with the short. This doesn't cover all possibilities but it might give you a place to start.
