The check engine light should not come on at all. If it does than you need to put it on a code checker, to find out the reason for the check engine light coming on. The light is known as the malfunction indicator light (MIL). When it comes on it indicates a malfunction in the system.
Thanks for your response. When the ignition switch is on, all the dashboard lights come on except the engine check light.
Usually I do one of two things to get it on. Reset the system by removing and replacing the battery pole to the terminal, or leaving the ignition switch on for a few minutes.
ell sounds like you have a bad ground or bad connection to the ecm. Check for green wires, bad engine to frame ground. Or perhaps this is something that a trained professional should check it out for you. The car should start with the M.I.L. light off or on and run in a closed loop operation. It is possible that the ignition switch itself is causing your problem.

When I turn the ignition switch on all the dashboard light comes on except the engine check light. This occurs when the engine is cold.
As a result the car does not start.
