Dads car wont start
 

Hi my dad has a mazda Xedos 9 (2.5 v6) which was a second car and as such never did very much. He went to start it in the garage and it started and then just stalled. Ever since it will not start. We tried to get a code from it but since it wont run we cant get temperature it just keeps coming up with (IIRC) an airflow fault. Iwas wondering if these cars have an immobiliser or some kind of cut off switch that may be stopping it starting. ANY help much appreciated. Chris
