The Vehicle Theft Deterrent system consists of the following components:
Powertrain Control Module (PCM)
Body Control Module (BCM)
Ignition Lock and Key
The Vehicle Theft Deterrent system is designed to disable vehicle operation if the incorrect key or starting procedure is used. The Body Control Module enables the crank circuit to the starter and sends a signal to the PCM if the correct key is being used. If the proper signal does not reach the PCM on the fuel enable circuit, the PCM will not pulse the injectors ON and thus not allow the vehicle to continue to operate, even if the crank circuit is bypassed. The proper signal is between 40-60 Hz and is measured using the DC scale on the DMM.
Inspect the GAGE fuse for an open. The GAGE fuse open casues DTC P1626 to set.
If the engine starts and then stalls, the Body Control Module is not suppling the appropriate signal or the theft deterrent fuel enable circuit is open, shorted to a ground, or shorted to a voltage.
Using the Freeze Frame and/or Failure Records data may aid in locating an intermittent condition. If you cannot duplicate the DTC, the information included in the freeze frame and/or failure records data can help determine how many miles since the DTC set. The Fail counter and the Pass counter can also aid in determining how many ignition cycles the diagnostic reported a pass and/or a fail. Operate the vehicle within the same freeze frame conditions (RPM, load, vehicle speed, temperature etc.) that the PCM recorded. This will isolate when the DTC failed.

if the car starts the theft code is not current or it would not start
remove the fuel pump relay and install a amp meter to the hot side of the fuel pump
and battery positive it should draw 5-6 amps
