I read the tutorial on pulling codes for free.. and decided to give it a shot out in the blistering cold. I don't have a CEL on, but I figured it would be helpgul to learn how to do this in the first place, or maybe I would end up with some secondary codes that wouldn't trip the light (pretty sure).
So here's the setup; I leave the battery terminals unplugged in the winter, save for when I start it. I understand that this would likely clear the computer of its memory right?
I started the car and let it run for like 10 minutes figuring this would be enough time for the computer to pick up on something.
I tried what the tutorial said, grounding the STI cable. It is the seperate wire from the main test harness. It's a light gray connector.
Well I grounded it, and turned the key to the on position (not started, but enough to have the radio turn on and such)
I heard the fuel pump click on and then off after a few like usual... then I'm supposed to see the light flash, but the light didn't come on.
So I figured that maybe the light was bad, but then I started the car and it flashed real quick as I started it (like usual) so the bulb is definitely not bad. I then tried with a multimeter, and I followed the instructions, plugging one end (I chose the red) onto the positive battery terminal. The other end I hooked up to the STO port on the main service port harness. Still nothing. I tried every setting on the multimeter, and the only thing I picked up on was the battery voltage (12.03 volts and dropping slowly; as expected) I figured then that maybe my ground was bad... but this is the kicker; I started the car... then proceeded to pull the ground off, and I heard my fuel pump do something, possibly flicker off and on again I have no idea. The point being, it made noise as soon as I pulled it from the ground. Which makes me think that it was grounded fine. I repeated this a few times, and it made a noise every time. I know I should be throwing some kind of codes, I have vaccum leaks everywhere that is related to the smog stuff. Anyway, I don't know why it isn't working, and I was hoping someone could shed some light on this for me. Thanks guys!

 

Just to be sure you're connecting it right, it should be like in the following diagram:



LUK if it works out or not on another try.

 

See from how I interpreted this website http://fordfuelinjection.com/?p=13 I didn't know to jump anything, just ground the sti. I'm going to go try that out in a little bit. Thank you!

 

I dont know if this can help . I just bought a computer OBD1 for $30.00 it came with a code book and everything. I found it at Checker/Kragen Autoparts. Was a sweet deal. Then from there i just opened the hood, Found the connecter like in the diagram above on the upper passenger side of the car. Walla.

 

I'm about to buy a code reader from somewhere [:@] I tried this other method, and still nothing. I was supposed to be looking for results coming from the multimeter right? The only things I could get, was a near 12 v reading, and .7 on some resistance. Neither changed with the key on. Have you done this before with a multimeter joel? I just unbolted the crossover pipe for the smog, so I won't be trying to pull codes for the rest of the day today; but I did everything correctly I don't know why it isn't working.

 

Buy a code reader! just make sure that you get the OBD I reader, you can do a cylinder check and all kinds of neat things with the code reader that I have, it's a greatly spent 22 bucks. Would definentally reccomend it.

 

You got yours from black snake right? I wonder where I could get one for cheap?
