Is this using the starter or?
Running engine. Starter can do the damage, too, but that's not guaranteed.

I am going to just put it back together and hope it runs... stories from this forum are leading me to consider that it's probably OK.

One more question, how can I pull power to the fuel pump to get it to crank without spraying fuel everywhere? I'm kind of embarrassed to ask but it's not immediately obvious.

It is #33 of the fuse panel under the drivers door.

On the XC70 last time I just unplugged all 5 injectors. However, I think they wouldn't fire again until I reset the codes.

I just started it, seems to run fine 😎 I found a copper crush washer on the ground afterward, wondering if it fell off the banjo bolt? Does anyone remember if you can see the intake manifold side copper under the banjo normally or is it buried in a recess? 😬 That's going to be fun if I have to get it on there

Check your fuel trims and see if it codes for a vacuum leak. Steel onto aluminum will seal pretty well.

Run it and replace next time.

Does anyone know what these parts are? Leftovers from the job... I think the plastic hose routing thing goes near the pct or somewhere near that gaggle of hoses but I can't remember
