The car starts after about 6 seconds ... then nearly dies (or actually dies). Then I restart it, and it nearly dies ... then catches ... and then runs fine.
Listen to how the car starts. This video captures it very well:

You don't have to watch the whole thing ... but that's what the car does when starting.
Yes, the leaning at 60 psi was very odd. It was at open loop. We did another experiment: we had the car hooked to the dyno A/F meter, started the car, and slowly increased fuel pressure. As fuel pressure went up, the mixture leaned out. 14.5, 15.0, 15.5, 16, etc.
