How come the check engine light does not come on in your 1998 Oldsmobile 88?

The light should come on when the ignition switch is turned to the on position without starting the engine. Once the engine is started it should go out, unless there is a problem with the emission's system. If it doesn't come on then either the bulb is defective or has been removed. If you just bought this car, I would suspect it has been removed to hide a problem with the emission's system. This is illegal.
