The first GIF is your ckp waveform with missing toggles. The second Gif shows a good ckp with 58 toggles.

But if it never sees tdc it will not start so if it is as the pic above shows (crappy design) then it will not start as it never sees tdc if you can pull the crank sensor without removing the transmission you should be able to rotate the engine and watch to see if a segment is missing but you wave form looks like the one he showed as well

Ray is correct. Also these motors are common for chunks of the crank reluctor coming off.
