Expert: INSTALLSUPPORT - 3/8/2008

Question
I drove my buick turned it off for about 2hrs. When I went to start it my battery was almost dead. everything in my car turns off automatically, so I didn't leave anything on. When I got a jump my battery charged up no problem,but my car wouldn't start. I noticed my security light flashing, it's never done that. what would kill my battery like that and why won't my car start?

Answer
Ok, bad news I am afraid.
This vehicle has a the PASSLOCK key
based engine disabling system.

A bypass is required to circumvent.
It has now locked down the fuel injector
rail, and you will need to tow it in to GM for
evaluation, and resetting.

Or,

You can get the PLJX bypass kit to get around
this issue.

This Passlock Bypass Module is designed to momentarilly
allow the engine to remote start by sending a proper
coded pulse to open the fuel rail passlock injector
cut off circuit.

The output from an alarm/remote starter
would then shut down the pulse, once it has detected
the engine has engaged, and preserve the integrity
of the passlock system.

That is it's designed purpose.

However, in your case, this input wire on the PLJX module,
instead of going to a momentary ground pulse from
an alarm/remote starter,
would go to a constant chassis ground, through
the bypass module, grounding out the PASSLOCK.
The PASSLOCK would then always be bypassed as long
as that wire is chassis grounded.

I can not speak about a damaged passlock system,
like if a thief has destroyed it, because I do not
get into this part of GM'S security application.
But as a happy coincidence to installing
after market remote starters, this does work on bypassing
passlock in most all GM vehicles we've run into,
including your year GM vehicle as well.

Also, this is a self learning, resistor sensing
and adjusting module. Once the VATS wires have been tapped,
you would press the program button to learn,
and it does. The car should then allow start
with any hardware store key.

It will on yours as well.

That's what will work on the 96 + Cavaliers.
