Pics didn't load but I was able to listen to the video.
What's your fuel pressure look like.
When wife's m54 e53 had a blown o-ring in her FPR I cranked about a dozen times about 8 seconds each before it finale fired up!
Check your fuel pressure at the rail key on no crank then turn off the key and monitor.
It should stay over 35-40 psi for an hour and then have 15-20+ overnight.
If it's zip overnight the fpr o-ring is blown or the check valve in he fuel pump but that I don't think will cause a non start.
Hoping it's the FPR. I did think I heard couple power strokes in that attempted start.
I'd have to look and see if I measured the tiny o-ring that was the trouble maker.
