Hi can someone please help ? I have just purchased a non runner ( must be mad ) I have replaced all coils and TDC sensor, fitted a different ECU complete with fuse box and key reconiser and key. All the electrics now work. Car will still not start, turns over ok , I am not sure how the imobiliser works. I have a light on the dash which says STOP when the Ign is on What does this mean ? also what is the sequence of lights for the alarm .
