Old posting but on the Passenger side under the dash where your Glove Compartment is there will be a green or blue rubber molded clip holder holding two connectors or one in some cases. Get the one with only two connections and place a paper clip to connect both together and then turn your key to the on position withou starting your car. Look at your Check Engine Light and it will flash telling you your code. It will flash three times and then begin. I believe the ABS light will flash for ABS codes correct???? anyone???? or the check engine light will flash????

for the paper clip trick when connecting the connectors, where will you insert each side of the paper clip into? like you know how the connectors have many different little slots in them, which one will they go into? need it asap

0 Faulty PCM (Powertrain Control Module)

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?
Thanks
