There is no fuse for the anti-theft system ! It receives it's voltage from the BCM . Do you know what a BCM is ? It is a Body control module .
The Passlock?"¢ System is provided in order to prevent vehicle theft if the ignition lock cylinder is forced to rotate or the ignition switch is operated while separated from the ignition lock cylinder case. If starting is attempted without authorization from the Passlock?"¢ System, the powertrain control module (PCM) will disable engine starting. Start disable may be in the form of fuel disable or starter disable, depending on engine application.
The components of the Passlock?"¢ System are as follows:
?€¢
The ignition lock cylinder and key
?€¢
The ignition lock cylinder case, including the Passlock?"¢ sensor
?€¢
The ignition switch
?€¢
The body control module (BCM)
?€¢
The security indicator on the instrument cluster
?€¢
The powertrain control module (PCM)
The body control module (BCM) contains the logic of the Theft Deterrent System. The BCM provides the battery positive voltage to operate the Passlock?"¢ sensor. The BCM also measures the voltage of the security sensor signal circuit. The voltage measured will indicate whether the Passlock?"¢ sensor has been activated and whether the resistance value from the sensor is a valid value or the tamper value. If voltage measured is in the valid range, the BCM compares this voltage, voltage code, to a previously learned voltage code. If the voltage codes match, the BCM sends a class 2 message containing a password to the powertrain control module (PCM). If the voltage codes do not match, or the voltage is in the tamper range, or there is a circuit fault, the BCM will not send the correct password to the PCM, and the vehicle will not start.
The body control system consists of a BCM and it's associated controls. Battery positive voltage is provided to the BCM from CLSTR fuse in the Fuse Block-left I/P. The module ground is wired to ground G201. The BCM is wired to the Class 2 serial data communication bus as well as discreet input and output terminals to control the functions of the vehicles body !
Now then Karen what problem is your vehicle having , no start an SECURITY light flashing or on solid ?
Now then

I just had this same problem with a '96 . do you have a vats key in your '94? you need to bypass the VATS system. read some of the blogs on this site and it will tell you how to do it. I fixed mine with a $2 resistor from radio shack.

2001 widnstar won't do anything. Won't start, can't shift

Have you verified this system is running the battery down? The system you describe is called the Remote Keyless Entry System (Electronic Time/Alarm & Control System - ETACS Module). It cannot be 'disconnected' without disabling other systems (intermittent wipers, Chime bell, Door Warning, Dimming Off Room Lamp, Seat Belt indicator, remote power door lock/unlock system, etc.)

you will have to take it to the dealer or a shop that does a lot of GM work. without a scanner and codes and service manual, you will not fix it.
