Low compression / High leak in cylinders. Help?
I posted earlier about my engine not starting, so it finally started but I'd still like to diagnose the issue. Long story short, after a week of sitting idle, I tried starting the car. It briefly fired up, but then promptly stalled. Now, when I attempt to start it again, the starter engages, the engine turns over, but it simply won't start.
Might be too much of an ask, Seeking advice from anyone who has encountered a similar issue with their 2.0 turbo. Any suggestions? Here's my current diagnostic progress, I'd like to diagnose as much as I can before I take the head off considering I'm renting and don't have access to the garage or driveway.
Here is a flow chart I created.

I got bad leak down results before a carbon cleaning (2 cylinders were 50%+) I think it was around 110k miles. Now that I got it done they are 5% or less in 3 of them with one being around 30% (was one of the 50%+ ones) so inspect them as could be from the leakage.

Thanks!
When you say carbon cleaning you basically took the intake manifold off and walnut blasted to clean the valves?
Also the one that still has a 30% leak - what do you suspect that is?
