are you looking at the pinout on this page??
the article i wrote for this has it.

my guess is that the ECU isn't reading for it.. what kind of chip is it?

i guess i need a little more info. and punctuation.

Ok. More punctuation. I'll try my best, but i make no promises. I dont have a chip and i havent looked at the pin outs on this page. I will however do that now.
