Car Alarms: Yukon Starting Randomly, gmc yukon, tail signs

Question
I have been having my 1999 GMC Yukon security light come on randomly. It will start flashing and then it wont start. If I let it sit with the key set to the on position for 10 minutes... the light eventually stops blinking and I can start it right up. I have done this for a year now. It probably happens once every 2 months. Im wondering if a bypass kit might help this problem. My Yukon also has an aftermarket alarm that was installed before I owned it. I assume the owner hooked it up because none of the features work. It will arm and disarm, plus it will set off the horn if you open the doors.
Would it be a good idea to remove the alarm too? Any advise would be great! Thanks

Answer
The aftermarket system is the least of your troubles here.
The ture problem now is the
PASSLOCK 2 system in the ignition will
eventually shut down the fuel injector system as
it is showing the tell tail signs now.

If left unchecked, it would run approx 500. for
the labor and parts from GM.

I get this one a whole lot
(as you probably have read.)
This is the most asked question these
days and yes, there is a solution that
will not cost you an arm and a leg.

Of course, & unfortunately, yes this
vehicle has a the PASSLOCK II key
based engine disabling system that is waring out
from use over time. This troublesome device is in
ALL 98+ GM vehicles, and yours is no exception.
To get around this, you will require a
GM IB-IM-PLJX bypass module to circunvent it and
KEEP IT THAT WAY!

A bypass is required to interupt PASSLOCK for
remote start applications. It is done by
grounding the system to allow it to start,
then re establish it for security usage.

This Passlock Bypass Module is designed to provide
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.

This is a self learning, resistor sensing
and self adjusting module. Once the VATS/PASSLOCK
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.
