Car was running fine, parked for a week or so and now dies immediately after start (doesn't stop like it's low on fuel, stops like if I were to turn the ignition to off). No amount of throttle changes this behavior. I did some Internet research and found that disconnecting the MAF sensor might lead me to the cause if it runs after disconnect. Exact same behavior when disconnected. While in the engine bay I found that if I disconnected the Boost Pressure Solenoid, it started up and ran (idle was a little high, but seems to run okay). The fact it's running when that solenoid is disconnected leads me to believe it's not (at least entirely) a fuel delivery issue.
Would you expect that the solenoid itself is the issue, or does that lead you to expect it's some other issue.

Some background history that MIGHT be helpful.
Radiator cracked sometime last year (saw low coolant light and stopped before engine got hot), finally got it replaced in Jan or Feb. Took for a test drive and was running fine, then stalled on us right as we left the neighborhood. (Threw a fuel delivery code, but only once, and I didn't take a pic. Didn't show in history or active codes)
Would not start. If it did start, would die shortly after (felt and seemed like fuel delivery issues, with a sputter stop). Let it sit a few minutes, and then was able to drive it home without issue. Have since driven it far and at freeway speeds without issues.

Car shows 2 engine codes, will provide images in comments.

None of these are NEW codes, it was running "fine" with them.
