Chevy cavalier wont start randomly! makes one click and a humm sound my lights come on the radio comes on but the car just wont start, ive had battery replaced along with the ignition switch, fuel pump,...
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.
