I also have a 1995 Mercury Sable that I'm desperatley trying to get back on the road. I got insurance and tag on it and broke the next day. Check engine light comes on after running a few minutes and runs bad with black smoke coming out of tail pipe. It seems like it's not shifting right. It will only do 45mph at 3000rpms. I tried to pull the code with a friends scanner and it wont pull. I've tried jumping the eec and using the scanner. My friends scanner is a snap on with right adaptor and computer card.

Maybe a problem with vss, vehicle speed sensor. I'll find a diagram.

The vehicle speed sensor is lower right rear of engine. Could be other issues? Don't know why you can't communicate with computer?

Would the vss cause the black smoke out of tale pipe when reving the engine?

I don't know? Can effect shift patterns. Sounds like it is flooding, not sure why? How long since over-all tune-up?

The ecc conection under the hood left side towards fire wall. Here's how I tried to jump it.

That hook-up looks good to me.

It's still not showing me a code. When I hook it up this way the check engine light stays on. That's why I got my friends scanner and it still did'nt show anything.
