Reading EEC Trouble Codes

I just picked up a actron code scanner (CP9015) and was trying to perform an KOEO test (Key on Engine off). I plugged my EEC test plug into my scanner set the HOLD/TEST button to HOLD reached into the passanger side of the car and turned my key to the "ON" position my injectors and fuel pump all kicked on like normal then I went to the scanner and switched the button to TEST. My Injectors seemed to do the same thing as the car does when you key on. But I get nothing the Scanner just sits their and does nothing. Any Idea's what I am missing here? I did not Start the car and run it before trying the Key On Engine Off test did not think that was nec. But let me know I never have tried to pull codes out the computer. thanks everyone.

Yup right by the strut tower has a spot labeled EEC Test which has the 2 connectors their I plugged them which fit perfectly in my scanner. Key On is when you turn the key forward and stop before you would turn to start correct? Because I get no codes for some reason.

Thanks

Finally got my KOEO codes which returned (111) or all good from that. For some reason it works if I have the audio set to ON and the scanner set to TEST right when I turn the Key to ON which then works. Thanks for the help guys now to test and find out why my check engine light keeps flashing and my idle rpms goes up to about 2500 rpm when the cars been running for about 2 minutes
