2002 Bonniville will not start

My 02 boniville sle will no start. turn key all electrical comes on including fuel pump but the car will not turn over.

Only thing I could think of is to see if you have power at the starter when the key is in the crank position. May be the starter solenoid if there is no power coming out of it, or could be a fuse if there is no power coming into the solenoid. A simple 12 volt light tester should be able to indicate the presence of power at either of those points.

There are a lot of possibilities with a no start. But the first one that I would guess at is either the starter is bad or the VATS wiring from the ignition cylinder is broken.

Security stay on?

Like the post above... What does the security light do?

Could be everything from the ignition lock, to the BCM right down to the starter its self...
