The inverted / faulty pattern is on the blue crank waveform.
At the Tdc event the larger segment is in the left of the Tdc event on my faulty car pictures 1&2.
But on the known good , lower picture 3 , the larger segment is on the right of the Tdc event.
I question the known good waveform... as the CKP signal is missing parts, since it starts / runs on alternative fuel have you looked into the cars source of fuel?
I endorse Brake Cleaner as a diagnostic Aid, A very crude one but never the less very Crude.
I'm guessing your customer is paying you to make it run on Diesel not Brake Cleaner ?
It is equal to Holistic Medicine, Horoscopes and Witchcraft.
Use more of the tried, tested & scientifically proved methods.

The rail pressure sensor is reading .5v Koeo , 1volt cranking and you Can see Pump waveform rising and falling. ( .8v- 1v. )
280 -300 rpm on live data, but certainly cranks fast enough to start
Signal taken at Ecu and sensor and giving the same readings.
New genuine Ford reluctor ring fitted. Only 1 listed , And crank sensor.
I haven’t physically checked the rotation of the engine when cranking, but it must be in the right direction if it starts with brake cleaner ?
But I will physically check
Had another car , same year/engine in today
and waveform was identical to known good
It seems like the reluctor needs to be fitted back to front. But it can’t.
Cam crank readings taken at Ecu and at sensors
I will check relative compression as well thanks
