I am having the same situation here. The check engine light comes on and stays on. Does this mean code zero? If not, how is code 0 represented?
[Edit] I figured it out: If the CEL is on before jumping then light staying on is code zero. if the CEL is not on without the jumper then no blinking means no code.

Does this mean that the light does not flash at all or comes on and stays on ( not flashing)?
This is the current state I have on my 1994 GSR. No start, the fault code I get (after jumpering the connector) is the Check Engine Light comes on but does not go out. I read that as a bad ECU.
Am I correct in my thinking?
