91 Loyale. Car runs well, but check engine light is on. I connect the read memory wires, but it will not spit any codes out. I've never had any problems like this before. The book says if nothing comes out, the ECU is bad. But the car is running fine otherwise, so I have a difficult time thinking the ECU is bad.
Any experience with this, or any ideas?

On my 92 Loyale the wires had to be disconnected to have the Ecu give a code.
If I remember well.
