Check engine light will not turn on

When you turn ignition to "On" position the engine computer is supposed to run some checks and turn on all the warning lights such as Battery and etc. and then they are supposed to turn off once the engine is running. What he is saying is that during this check, the check engine light does not light up. He is asking what does this mean? Does that mean the ECU is fried and no good?

ok most of time its a fuel system issues a lot of the time go to fuel cap pull it off inspect the seal around the cap any tear or signs of wear. Replace if necessary. after 5 or 6 drive cycles it will turn off. if it comes on again or stays on, go to your local part store and have them read the code with the scanner. its free. you may have to replace the cap. They might also tell you its an o2 sensor, ask them to show you on the car where it is. then buy a 02 sensor and replace it your self. saving you about a $100. remember any light that comes on in your car go have it check out and do the work yourself. saving you lots of cash.
