What is the function of the cam shaft sensor I have a 91 Buick Regal?

Older cars used a distributor to control the firing of each spark plug. The proper setting was mechanically set. The newer cars use a computer to do this. The computer uses a crankshaft sensor to know its position and a cam shaft sensor to know which piston gets the firing pulse. The failure of either one will result in the engine not starting.
