No the security light does not flash when cranking.
Chevy Mechanic: jim, ASE Certified Technician replied 8 years ago
We need to determine if the problem is spark related or fuel related. You can use a alternative fuel source and see if the vehicle will stay running. If you are not familar with this procedure it can be dangerous, and wouldn't recommand it. To check if it is a spark problem you can purchase and install a spark tester. It looks like a spark plug and you remove on of the plug wires and install the tester. Most part stores have these.
