Just thought I would add a note, when my Gal was in fault condition the door LED did not light, and this shows that the correct key has been inserted and the immobiliser is disarmed, and the fuel pump can be heard priming when the key is turned to pos 2, ready to crank, with normal dash lights and indicators on, so its good to know this to eliminate the immobiliser. I guess the immob is fed from relay 30, and thats why the diagnostic kit could not get a response from it when tested, anyway thanks again for your help and suggestions...it all helped to solve the problem!!
