Did you test the pin?

[Danfinny]

I did and got nothing from the wire. it is Pin 3 on the ecu according to the ecu

pinout. other problems to i think because i cant get a throttle signal either. the sensor reads out fine though. ahhhh i hate wiring

If you capable I would check back through the board but if not and even if so the easiest way would be to get a ecu you know is good and check it out.

 

ka ecus aren't expensive or hard to come by

[Danfinny]

OBD II ones are at least at the junk yard lol.

I keep forgetting the coast difference, ka's are way more cheaper/plentiful here. Still vote you check another ecu, even if it's just a buddies or w/e, takes 5 min to plug it in and know 100% where the prob lies.

Look on Zilvia.net. They've had so many partouts in the past few months it's retarded. It's an OBD II so it's 96-98, obviously. Shouldn't be hard to find something for $50 or less.

 

Is it a 1995? If so, it's wired slightly different than the other OBD I's and isn't a real OBD II either... pain in my ass.
