Hi mate, the MAR position is the first ignition position, so the ign lights are lit, but the car hasnt started.

To reset the ECU, you can disconnect the neg lead from the battery and touch the neg lead onto the positive battery post. DO NOT SHORT THE LEADS TOGETHER!!!!.

alternatively, you can disconnect the battery for a period, I normally do it overnight.
