No Crank, No Start After Clearing Check Engine / Security Codes?
What is your question?
2002 BUICK REGAL GS Supercharged: Solid Security light and solid Check Engine Light lit for over a year with the engine running fine before scanning. I scanned all systems with Blue Driver OBD2 Diagnostic Scan Tool while the engine was running. Scan revealed confirmed codes P0102 and B2958. It also displayed historical Security codes B2960, B2957 and B2961. I selected "Clear All Codes" and then the engine died. I attempted to restart the vehicle but the vehicle only clicked, no crank, no start. I attempted the GM Passlock relearn procedure but it did not work. No crank, no start and the solid Security light, Check Engine light still remain. I scanned the system again and current Security code B2958 and historical Security code B2960 are the only codes that remain. Battery is fully charged. Can a scan tool really cause a vehicle not to start? How do I fix this?

Is this clicking noise emanating from the starter perhaps?
Can the engine be turned manually (using hand tools) ??

Not really concerned with the scan readings - at this time.
With the key in the "on" position, I can hear the fuel pump priming. When I turn the key forward to crank, I hear a relay in the dash click one time. The car literally went from running to not running right in front of my eyes and the only action I had taken before hand was running a scan tool and clearing codes.
Most common problems related the the Passlock family involve the Passlock sensor. The sensor is part of the ignition lock cylinder on Passlock I and Passlock II systems. The antenna is the Passlock sensor on Passlock III systems. If these sensors fail, the proper repair would be to replace the failed part and perform a theft system relearn
procedure.
Relearn Procedures
The Passlock family has two basic relearn procedures—a ten-minute procedure and a thirty-minute procedure—and which one you use depends on the system and what components have been replaced.
The ten-minute procedure involves trying to start the engine. If nothing happens or the engine starts and dies, the security light will be flashing. Wait ten minutes. The flashing light should go off or illuminate without flashing. When it does, turn the ignition off, wait twenty seconds, and then try to start the engine. If it starts and runs, everything is okay. If you get the same result as previously—nothing happens or the engine starts and dies with the security light flashing—wait ten more minutes.
You will now begin the thirty-minute relearn procedure, which is just the ten-minute procedure repeated three times. After turning the ignition off for the third time and waiting for twenty seconds, the engine should start and run. If it doesn't, there may still be something wrong with the system.
After the learn procedure is completed and the engine is running, the security light may stay on steady for a few minutes and then go off—this is normal. Depending on the system, replacement of key components will necessitate that a relearn procedure be completed. These include the ignition lock cylinder, Powertrain Control Module (PCM), Body Control Module (BCM), or Instrument Panel Cluster (IPC).
Unless the VATS control module is replaced, there is no relearn procedure for the VATS system. A new VATS module will learn the resistor code the first time it is powered up. Once the module learns its code, there is no way to relearn it. New ignition keys must always be matched to the learned code in the VATS control module. If all keys are lost and the VATS code is unknown, then use trial and error to find the correct VATS code. (In some cases, the VATS code may be available from your local General Motors parts department.) If the incorrect VATS code is read by the control module, the system will not allow the engine to start for four minutes—even if the correct code is received.
SOLVED: I removed the radio/HVAC bezel and steering column top/bottom covers to gain access to the ignition cylinder. One of the small white wires on the ignition switch that sends the resistance value from the key pellet to the GM Passkey system was broken. Before fixing anything, I attempted to start the car and it started right up with wire broken and the security light lit. I soldered the wire together. Car now starts and runs fine with no Security light and no current security codes. I'm still not sure what the cause of the original no start issue was. It truly seemed like the engine dying and not restarting correlated with clearing the security codes. Obviously the wire damage was a long standing issue that needed to be corrected. Anyways, thank you for your input. It is truly appreciated.
