Passlock dont starter - 1997 Oldsmobile Achieva

it's a manual means my transmission is manual transmission?
with a left foot clutch ,the clutch switch is bad above the pedal clutch
that switch enables the starter relay just like all cars, manual
so you an not start engine in gear.

those other problems are other causes.
IMMO key must not be ignored. padlock
thee users guide tells you what the lamp does. (lost that?)
lost the second ignition key? from when car was new.
some cars dim HL lamps to have extra power to crank the engine, a super good features on all cars with it.
you just buy a dead car, or did it just fail out of the blue.??????????
learn what RAP is in the manual.?
key off radio works for delay10mn them or ends door open
page 2-18 in the manual

now IMMO words same manual free, to all chev. owners.
Page 2-15 actual
to start the engine closes door or IMMO Passlock
will fail.
Your vehicle is equipped with the Passlock®
theft-deterrent system.
Passlock®
is a passive theft-deterrent system. Passlock®
enables fuel if the ignition lock cylinder is turned with
a valid key. If a correct key is not used or the ignition
lock cylinder is tampered with, fuel is disabled
During normal operation, the security light will go off
approximately three seconds after the key is turned to
RUN following an engine start.
If the engine stalls and the security light flashes, wait
until the light stops flashing before trying to restart
the engine. Remember to release the key from START
as soon as the engine starts.
If the engine is running and the security light comes on,
you will be able to restart the engine if you turn the
engine off. However, your Passlock®system is not working properly and must be serviced by yourdealer.

but the clutch switch is failing and can be jumpered easy, your paper clip. some switches have adjustment or are just fell loose.

Do you know how complex the electronics are on that vehicle ? What happens when you turn the key to start position ?
Circuit Description
Moving the ignition switch to the start position applies ignition voltage to the switch side of the STARTER relay. The powertrain control module (PCM) receives a serial data message that crank has been requested from the body control module (BCM). The PCM then verifies that the transmission is in the Park or Neutral position and that theft is not active and grounds the control circuit of the STARTER relay. Battery voltage will then flow through the switch side of the STARTER relay to the S terminal of the starter solenoid, cranking the engine. Ground for the starter is supplied through the engine block.


Hook up a scan tool an check for codes . All system scan ,all control modules on the vehicle .

Passlock™ System
The theft deterrent system has been incorporated into the body control module (BCM). The theft deterrent system is provided in order to prevent the vehicle operation if the correct key is not used in order to start the vehicle. The ignition key allows the lock cylinder to rotate. The cylinder rotation produces an analog voltage code in the Passlock™ sensor. This voltage code is received by the BCM. The BCM compares the voltage code to the previously learned voltage code. If the codes match, a serial data message is sent from the BCM to the powertrain control module (PCM). The message enables the fuel injector operation.
The design of the Passlock™ system is to prevent vehicle theft by disabling the engine unless the ignition lock cylinder rotates properly by engaging the correct ignition key. The system is similar in concept to the Passkey system. However, the Passlock™ system eliminates the need for any key mounted components. The components of the Passlock™ system are as follows:
• The ignition lock cylinder
• The ignition switch
• The Passlock™ sensor
• The BCM
• The security indicator
• The PCM


Passlock system does not keep the starter from working . Try putting the vehicle gear selector in neutral an see if the starter works then.

There is no direct connection from the purple wire to the ignition switch . This is computer controlled , Ignition switch is a low voltage input to the BCM - body control module . When you turn the key to start the BCM see's this an sends a message on the serial data network to the PCM / ECM - engine computer . IF the PCM / ECM see's voltage from the Internal mode switch in the transmission it knows it is in park or neutral an see's no problems with the anti- theft system it will energize the crank relay sending Battery voltage on the purple wire to the starter solenoid . You have no clue of the complexity of this system , do yourself a favor an take it to a qualified repair shop . Before you make matters worse . You already spent money on a new starter needlessly .

Circuit Description
Moving the ignition switch to the START position signals the body control module (BCM) through discrete inputs from the ignition transducer that engine crank has been requested. The BCM verifies that theft is not active and sends a serial data message to the engine control module (ECM)/powertrain control module (PCM) requesting engine start. The ECM/PCM receives a 12-volt signal from the park/neutral position (PNP) switch or clutch pedal start switch notifying that it is safe to start the engine. There is a splice on this circuit in the fuse block-underhood that supplies power for the starter relay coil. The starter relay coil control circuit is then grounded by the ECM/PCM closing the switch in the starter relay suppling 12 volts to the S-terminal of the starter. Ground is supplied through the engine block.
Vehicle Theft Deterrent (VTD) Description and Operation
Circuit Description
The Passlock?"¢ system is provided in order to prevent vehicle theft if the ignition lock cylinder is forced to rotate. The Passlock controller reads the coded Passlock?"¢ data signal. The data consists of a voltage generated by a voltage divider network created between the Passlock assembly and the Passlock?"¢ controller. If the data is correct , indicating rotation of the lock cylinder with the proper mechanically cut key, then the Passlock?"¢ controller sends a password to the Powertrain controller over the class 2 bus to indicate that starter engagement should be allowed. The Passlock?"¢ controller also interfaces with the driver displays subsystem to indicate, via a Security telltale, the Passlock?"¢ subsystem's status and acute subsystem failures.
The components of the Passlock?"¢ System are as follows:
?€¢
The ignition switch

?€¢
The body control module (BCM)

?€¢
The security indicator on the instrument cluster

?€¢
The engine control module (ECM)

If it doesn't even click and the battery is Ok it could be a fusible link.

This could also be the anti theft security system (passlock) shutting down the starter. This is a common GM problem that effected Escalades from 1999 to 2007. When the anti theft starts to fail, it gets confused and locks YOU out instead of just theives. The fact that you can start it at the starter helps prove this "theory". Another indicator would be if you saw a light on the dash that says SECURITY or a picture of a little car with a padlock thru it. This site explains the whole security thing and offers DO IT YOURSELF ways to fix it.

his vehicle has a the PASSLOCK II key
based engine disabling system.

You can attempt to put the key in the ignition,
turn it on to just before cranking and then leaving
it that way for 10 mins. After that,
some PASSLOCK systems will re learn the code
and allow for starting. But if not, the system
will either need to be seen by GM or, a bypass module
is required to circumvent.

If left unchecked, it will continue to lock down
the fuel injector rail, and you will need to tow
it in to GM for evaluation, and resetting anyway.

Bothersome, but can be fixed.

I suggest the PLJX bypass kit to get around
this issue. www.PASSLOCK2.com

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 would on yours as well.

You might want a car alarm installer to do this
for you, the fair rate being around 50. to 75.
for labor.

Are you sure it is a starter? It could be a theft deterent concern.These vehicle were noted for the ignition lock cylinder/passlock sensor problems.try to start vehicle if it does not start leave key in the on position for 10 minutes.if it starts then you have a passlock problem.auto parts warehouse.com if you need a starter.

Is the security light flashing when you are trying to start? May have a passlock issue if the reset process did not work.

In your BCM (Body Control Module) there is integrated a TDM (Theft Deterrent Module) that is probably faulty. I saved my car in the exact same situation with this: http://newrockies.com/vatsbypass . It was the only way. The author says it works with PassKey and VATS, but It works perfectly with Passlock too as the only difference between those 2 systems is that in PassKey the resistor is in the key, while in Passlock, the same resistor is in the lock ...that's where the names come from... :)

it has a passlock 2
