Car cranking but not getting spark (to start)

Car cranking but not getting spark (to start). Replaced fuel pump n filter, crank sensor (dropped tranny) and cam sensor. Still not starting. We called dealer service dept and was told sometimes there is a shut-off switch. Guessing they mean an emergency fuel shut off switch. Looked online, asked several places and bf's brother is mechanic and we can't seem to get this car working. First, could you tell me where the shut-off switch is for my vehicle and what else it could be that the car isn't starting. Thanks for the info ahead of time
