How does the PassLock system on a 2000 Chevy Silverado work?
by David Clair. The 2000 Chevrolet Silverado is equipped with the General Motors Passlock theft-deterrent security system. The system disables fuel to the ignition if a valid key is not used when attempting to start the engine. If the Passlock system is activated, the Silverado will not be able to be started until the system is reset.
How does the PassLock shut off the fuel pump?
I have now learned that the PCM also shuts off the injectors as well as the fuel pump. This is done via the Fuel Enable circuit to the PCM. It can be duplicated with a 5v 50hz sine wave on Passlock systems which is probably all the newrockies device does.

Can a PassLock bypass disable the fuel injectors?
The PRO Module is a FULL Passlock Bypass Module instead that goes right to the heart of the problem and solves it by reproducing the proper output signal that the PCM (onboard computer) uses to enable the fuel injectors. This means you can disable and often remove the ENTIRE immobilizer system from your car, to plague you no more!
