Cant pull check engine codes

Hey all,

I have tried searching around, and I have tried pulling the codes by turning the keys to the on position then off 3 times but my check engine light wont blink at all. Is there a certain amount of time I am suppose to keep it in the "On" position for? Also for the "Off" position, is it the position at which point you can take the keys out? I really appreciate any help! Here is some info.

1996 Jeep Grand Cherokee Laredo 6 cyl 4.0L engine.

Try On-Off-On-Off-On, that's off only two times instead of three.
