Hi Mathew,thanks for getting back,have you tried starting in neutral?(if it can),most autos these days have a shift interlock as well as a start inhibitor ,to prevent it being started without ones foot on the brake and/or in any gear other than park or neutral,the starter will only work when a criteria is met i.e. in park or neutral,foot on brake etc.(bmw will only start when the doors are closed as well),have you tried jiggling the shifter in/out of gear or tapping the brake pedal,the relays/solenoids that make all this lock-out work can sometimes jamb,preventing the system working properly and if given a little encouragement can revert to start,also check the owner manual for a backdoor,sometimes the lockout can be bypassed for service procedures,may get you going,let me know ,cheers stew
