pulled into my driveway the other day and then the next morning no start just crank. i have fuel pressure and maf counts but 0 spark on my handheld tuner. i replaced my coil packs, cleaned both crank and cam position sensor and checked all of my grounds and still nothing. i do have 12v running through all of my coil pack pigtails so there's something stopping the coil packs from activating. any ideas? 2001 GT
