Alright- I don't even know where to begin searching for this one and it has me stumped.

So this happened about a week ago and again today, only worse and leaving me stranded.

Car is a 2002 LS1 Camaro A4

Issue is:

I go to start the car and it immediatly doesn't idle, it dies, fire it up, rev it up, same thing (sounds and runs great, but just straight dies with no throttle applied)

ok cool- go to start it again, now all I get is a click and it wont turn over, ok, turn the key off, go to turn it back on and now absolutely nothing- gauges dont sweep, no lights, no windows, no door locks- acts like a total dead battery

Ok- pull the key out of the ignition entirely and wait...as I wait, I all of a sudden I get a half sweep with the gauges and the seatbelt light comes on and stays lit up

during this period, key fob doesnt work nor does anything electrical (locks, radio, etc)...wait 5-10 minutes- put the key in and turn to run and everything is functional as if there is no issues...go to start it and all I get is a click like it has a dead starter.

Now for the super loop...I finally do get it to start and there is a loud whinning coming from the fuel pump area inside the car, the car still refuses to idle without the throttle being depressed. Car dies and repeat all over again....

Is this a BCM issue? In my 96 when I had a bcm issue I had trouble with the radio working when it wanted to- I haven't had any of those intermittent symptoms with this car, and I certainly never had any idle/running issues like this from a BCM before...

I'm stumped?

 

Now I am starting to wonder about a bad ground

The battery is brand new as of 2 weeks ago, but I got in the car again yesterday and the security light was flashing rapidly and making a dead battery clicking type noise.

I through the charger on it and it immediately read "reconditioning" indicating the battery is in poor shape... then after about 5 minutes, it showed 80% full- I got in the car and it fired up but didn't want to hold an idle <<< this still confuses me.

After about 8 startup attempts she fires up no problem and holds idle. I tried about another 10 times just to make sure it wasn't a fluke then took it on a hard ride around the area.

She was completely fine for the drive and laid rubber no problem...I get back, toss the charger on, and it is reading "low" but she fires up no problem

Now I am beyond stumped... I undid the terminals on the battery and they look good and honestly, the car is in damn good shape, so it doesn't look like anything really has corrosion on it.

I'm going to clean up a few ground points today, but nothing looks bad at all??

 

Might be a bad battery or charging issue, I would have both battery and alternator tested. If they are fine, I would start cleaning grounds

 

the only thing is in my mind- if it was a bad battery or alternator, would it fire up first time and just not want to idle?

I have a buddy coming by today to test the alternator / battery for me. Im still stumped though
