I left those loose on my car and it caused issues. To clarify yes I am talking about the two nuts that hold the injector wiring to the fuel rail.

Super true. Had an "experience" with this right after the S50 was running.

does that thing have a cam sensor? If you have spark and fuel, time is all you are missing although your dry compression #s are pretty low. Vanos failure?

Apology for not reading the whole thing.

180 out of timing?

[Danny]

Fuel pressure is still solid at 50psi while cranking.

[416stroker]

weak fuel pressure? Just enough to make it pop maybe thats all?

[Danny]

This seems stupid but see if the 2 10mm nuts holding the injector wiring on are tight.

The two nuts that hold the fuel rail to the injector harness? Those have always been missing, never been an issue.

That is not wanting to start, that is a misfire.Hear how it slows the cranking like its getting punched in the stomach? Did you try starting it on ether? Are your plugs wet with fuel when you pull them out? If you are getting fuel and the engine is not starting the plugs should be wet. What does your crank sensor look like? any damage to it or to its wire all the way back to the harness? Is the sensor gap correct?

Yeah I tried on starting fluid and it backfired through the intake. Plugs are wet indeed. Wet with fuel. Sensor looks okay, the gap is the same as its always been, its tight in its holder.

I didn't see if this was mentioned already or not, but have you tried another ECU?

Yes indeed. No change.

The popping in the vid sounds like either unmetered air or shitty spark timing to me.

Its a backfire type sound through the muffler.

Here's a video of it cranking, you can hear it almost wanting to pop over.
