Crank position sensor (equivalent) is built into distributor. I would pull distributor cap and make sure distributor is rotating. Sometimes roll pin on distributor gear will shear for no apparent reason. Easy fix. If it’s rotating, you can either load the parts cannon ( coil, distributor, ecm, and ect) or do your detective work. I have owned 7 or 8 fi 460 fords and still own 3. Sudden no spark has nearly alway been distributor related, though one time it was the ecm. Also, one time it was the single 12 gauge wire ( on motorhome) on positive battery post wasn’t making contact
