passlock 2 problem

I bought a command start for my 2003 GMC 2500 from Canadian Tire.  I also bought a bypass for the Passlock 2 system.  I wired in the bypass (xpresskit pljx) and when I programmed it, it seemed to read the resistor properly (the lights blinked exactly the way the instructions said they would).  However, when I hook up the command start and attempt to start the truck with it, the truck will start but only run for a second and then shut off.  This truck is a base model (no power locks/windows and no alarm) but is there something in the key that is making this not work?  I have read about a transponder but am pretty sure my key does not have a chip in it.

If anyone has any idea what might not be working, I would greatly appreciate some advice.

Thanks.

Hello, I have a question:

I just installed an Avital 4103 car starter/keyless entry to my 2000 Chevy Impala, now everything works according to instructions except for engine start, I believe this is because of the factory passlock II, I checked the vehicle wiring diagram but I can't find where exactly to add a relay and resistor to bypass it.

Anyway I ordered a xk01 bypass module and I was observing the install guide, it says I only need to connect the 4 wire harness and purple wire to OBDII purple wire to start the engine via the remote starter transmiter. Is this really all I need to do to bypass the factory anti theft device? Where do I connect the purple wire from the 4103 (tach signal) to ignition coil white wire or to xk01?

Thanks. 

The remote starter I have has an automatic tach learning feature (I also have the tach wire attached to the back of the gauge cluster).  According to the remote starter it learned the tach but I could be wrong.

never heard of canadiantire selling command starts. are you sure its not prostart?

if its a prostart you will need to manually program your tach

To Graywire: 

The XK01 flashed with AMDL V6.0 firmware will handle the Passlock2 and everything else listed in the chart with just the one connection to the OBD2 connector. (  I still don't trust D2D, so I make all the W2W connections. )   The XK01 does not output a Tach signal so the 4103s' tach wire should be connected to the White wire at the ignition coil.

It is a prostart.  I will look into the tach wire tonight to ensure a solid connection and I will manually program it.  Is there anything I have to do with the key in order to bypass the passlock/transponder or will the bypass module I bought (xpresskit mentioned above) do everything I need to do?

Thanks for the help.

The 2003 GMC Sierra pickup truck has the Passlock2 immobilizer system.  The DEI PLJX will bypass that OK.  The key does not have a transponder chip.

If you are having problems with the remote start, are there any security type lights on the dash?  Did the system Tach learn OK?  Does the ProStart have a Tachless Mode you can switch to and try?

Keeping the Tach wire inside has its' advantages.  Do a search on it.  I believe there are a few posts on
the easy way to locate / reach the wire behind the cluster.

Here is a note from Bulldog for the Tach signal:
 TACH  WHITE   @ PCM, GREEN PLUG PIN 36, See NOTE *3 
 NOTE *3 The PCM (Powertrain Control Module) is located in the LEFT FRONT of the engine compartment
 to the left of the fan shroud. On DIESELS the TACH wire is at the BLACK PLUG, PIN 55 and on the hybrid
 models the tach wire is in a GREEN PLUG PIN 35

If the ProStart is capable, any un-common color wire at any Fuel Injector should work also.

Thank you for your reply Kreg357

Ok I'm going to try D2D first and if it does not work I'll do W2W. I ran the PURPLE / white wire to the ignition plug (white wire) in the engine comp. I hope the  Avital 4103 reads the signal, If it does I'll just have to deal with passlock II but the xk01 should take care of that.

I use iDatalink modules and have not seen that problem.  Could be a less than perfect connection.

Verify all your connections are well soldered and the remotes starts' ground wire is good.
