Iíve had the MSD 6014 for a year on my blow-through turbo 4.8L Mustang. Since new, I keep getting crank sensor failures. Iíve used GM sensors as well as the auto parts store versions. Nonetheless it throws an alert and no start condition. Iíve gone through my harness and installation wiring a few times and canít find anything wrong. Checked voltage at the coil pack harness as well as the crank sensor. Iím thinking possibly a faulty box. Iíve had it over a year and this is an on going problem. When it runs, it performs excellent, but has left me stranded a few times. Iíd like to figure this out.
