if the CEL doesnt light up when you insert the key the bulb may be burnt out or removed by a shady previous owner.

This was just covered a few days ago in a different thread. In my manual for normal it shows 8 blinks which means continous blinking. (every .25 second)
Are you using the diagnostic box under the dash or under the hood? Try both to see if any different.

Make sure the following settings are correct when connecting the diagnostic pins.

"In order to read the code the battery must be 11v or higher, throttle valve fully closed, transmission in neutral position, and AC turned off."
