I had the same security light problem with my tahoe. It is a passlock system problem. The starting and stopping of the engine is a passlock (security light) problem. Being that the security light is ON and not blinking indicates a module problem or an ignition key switch problem. Is it blinking? You need a modis or gmtech2 or 1 scan tool to diagnosis this problem. It probably is the resistor either in the passlock module or the resistor in the ignition switch...

Try turning the keyON but do not crank the engine. Let it stay like that for 12 minutes - exactly. Then turn key off for 7 seconds - exactly. Then try to start the engine..

 

Have you figured out where that broken wire leads to? I did the same thing pear69 suggested when my security light problem came up and it worked great for me.
