It should come on when you turn on the ignition without starting the car. If it does not the bulb is blown or it has been disconnected. Some unscrupulous sellers do this before selling a car with emissions problems where the light is on. If you just bought the car, have the bulb checked and if you find after replacing the bulb or connecting it, the light stays on demand a refund or repair of the problem from the seller. Get written proof of the condition of the bulb. If they refuse contact your state Attorney General for advice on what to do. It is illegal to sell a car with a non-functioning MIL (check engine light).
