Chevy Lumina Car Repair Help

1997 Chevrolet Lumina. Question: I am having trouble with the Cruise Control. The cruise control just stopped working. I have checked it out with the Haynes Manual and could not find the answer. Does it have a switch on the brake pedal that affects the cruise control?

1997 Chevy Lumina that I can't get started.I can turn on the key, all the lights are on, but when I try to engage the starter it does nothing and the headlights blink off.  I can jump  the starter with a screwdriver and the car will start but the engine will immediately shuts off.  I'm thinking it's a key chip code problem, but we have tried two different keys.
