Hi guys, my car has given me a headache this week. First car stalled, then refused to start. Put a scanner on computer, came up with cam/crank sensor fault, so replaced both cam and crank angle sensors and with a brand new harmonic balancer. Started car, worked, let warm up, turned car off and tried to start it, got nothing. checked for fault codes again, fault 47 18x input missing or grounded? what does this actually mean and how can i go about fixing it???
