Well, you're mistaken.

From the service manual;

The passlock sensor data supplied to the BCM is in the form of V-codes or voltage codes. When the proper ignition key is turned in the ignition switch, the correct V-code is supplied to the BCM. The BCM responds by sending a serial data password to the engine controller allowing the engine to run.

Under a tamper condition, a specific V-code is supplied to the BCM. The BCM will send a class II message to the PCM disabling the fuel injectors.


No mention anywhere of disabling the fuel pump. I thought the same until I read the service manual.................

REWARD EXCELLENCE!
