Follow the cable from the reader coil around the key barell. From that box will be a brown wire and a loop connection that goes to earth. Bet your one doesn't.
The loop is good, both brown wires are grounding and have pulled the kick panel off to un cover the earth below the fuse box. Any other earths I should check?

Im stumped on this..it stopped starting randomly over 2 months ago, was running fine before that. A mechanic couldn't connect to ECU so couldn't diagnose the problem so got the car towed home and sent the ECU away to be checked> they also told me that they couldn't connect to it so best bet was a fried ECU so took a punt on a second hand ECU from the UK. Trying to connect so I can mate the new ECU to immo...the adventure continues..
