For the longest time the vehicle will randomly lose all battery power. (preventing the car from starting) It happens overnight or in just a matter of hours. Sometimes goes weeks without incident, or can happen everyday for a month. I have a jumper pack that jumps the vehicle with no problem. Once i hook it up to the jumper, the car cranks like it has a new battery. Gone through 3 batteries. All work great for a while, then the problem comes back. Thought it may have been the stereo since the cd player was broken and the cd spun ALL the time. Replaed that with aftermarket Pioneer and proper wire harness. Problem still exists. Im looking for a way/proceedure to isolate the problem and either fix or bypass it. Im just at a loss with this thing. Dont know what else to try before the mechanic starts selling me parts. Thanks for your help. This ever happen to anybody else?
Well, this is how to check for a short ! hook a test light to negative post on battery, then hook other end to the neg, cable itself, . leave light hooked up, and remove negative cable from battery with light still hooked up to it. give the unhooked light and cable about 5 minutes. if light glows after neg, is disconnected from battery. you have a drain. to find it, leave light hooked up. start by pulling fuses when you pull a fuse and the light goes out youve found what circuit is causing the drain.

You need go to a NAPA parts store or equal store,and have them check,and show you your out put voltage on your alternator.If it is working fine it will be between 13.65 to 14.25 volts.Also have a 2 amp battery charge on the battery to get a good deep charge,fast charging only give a surface charge that doesn`t last.Without the alternator charging,the battery will run down and down and down.The battery will need the deep charge to restore it`s reserve power,not just surface power.If the alternator is ok,then you have what is know as a draw on the system,something is drawing enough volts to drain battery,even though key is out if ignition and nothing is left on.Cocks,and clock radios cause this a lot of the time,then there is delay dome lights that stay on,and in the day time you would not even notice.The alternator it self can draw a battery down while not driving the car.The voltage regulator or a bad diode in the alternator can do this.If I can help [email protected]

Ok then, from your description and the
make/model/year of the car you have there,
it appears you've reset the VATS.
The car's security immobilizer
reader at the key switch
does not recognize the coded
chip in the ignition key any longer.
You can try to put the key
in the ignition, turn to the on position &
wait at least 10 min like that.
(Do not turn off the key switch before
10 minutes as elapsed!)
Once done, the key is re-programmed and
should allow the fuel injectors to work again.
The car would start now if corrected.
In some cases, the VATS (GM'S VEHICLE ANTI THEFT SYSTEM)
will re learn the code this way, and will then
allow the restart, however if this does not work,
then you can simply tow it to any GM vehicle dealer
to have the service department re code it.
There is a permanent solution though.
Adding the PLJX Self learning Bypass module (59.95)
will bypass the PASSLOCK system in your vehicle
for good. See this at www.PASSLOCK2.com
Good luck I hope method 1 does the trick!
Here is the 30 min relearn:
Ignition keys relearn takes about 30 min to do. 30-Minute Learn
Procedure 1. Turn ON the ignition, with the engine OFF. 2. Attempt to
start the engine, then release the key to ON; the vehicle will not
start. 3. Observe the SECURITY tell tale light. After approximately 10
minutes, the light will turn OFF. 4. Turn OFF the ignition switch, and
wait 5 seconds. 5. Repeat steps 1 through 4 - two more times - for a
total of 3 cycles of 10 minutes. 3x10 = 30 minutes. The vehicle is now
ready to relearn the Passlock Sensor Data Code and/or
passwords on the next ignition switch turn from OFF to CRANK Important:
Turn the Ignition Switch OFF. The vehicle learns the Passlock
Sensor Data Code and/or password on the next ignition switch transition
from OFF to CRANK. You must turn the ignition OFF before attempting to
start the vehicle. 6. Start the engine. The vehicle has now learned the
Passlock Sensor Data Code and/or password. 7. With a scan tool, clear any DTCs if needed. History DTCs
will self clear after 100 ignition cycles. Without a scan tool you may
have momentary starter interruptions while history clears itself.

2001 Impala LS 105K mi My stereo amp under the rear deck was always warm even if the car sat wall night warm means power is being pulled even when the stereo is off. I pulled the power plug on it my battery quit dying. Must been something shorted inside the amp maybe the sensing circuit A quick fix I put a relay on the hot line gong to the amp so it goes on and off with the key. No more dead battery.
