Try clamping the fuel return line with the appropriate tool that wont damage line and see if it improves if so you need a fuel pump or pressure relief valve.I know you said you had fuel pressure but you took that reading while vehicle was idleing so you cant check for pressure in above idle conditions.Is your air cleaner assembly as original with no holes or leaks from air box to throttle body?Its more likely to be a mass air flow meter.This problem occured to my vette while i was on holiday there.cost$89 exchange.good luck

What is an OBD code 51 on 1990 toyota corolla 1.6L 4A-FE and how to test?

Well this answer is going to be a bit fuzzy.
Code 51 is for a switch signal issue. The possible causes are the throttle position switch, the neutral safety switch, and the ac compressor switch. One of those three is not sending a signal to the computer. So if its the ac switch, you know why.
But all three would need to be checked out.

Battery died (after lights left on) . Had a successful jump but now it stalls in idol....but will start right back up.

Give it a little time. the computer in your car needs to re-learn its idle. very common in jeeps and big time in Fords. Check the trottle plate as well as that could be dirty and your computer can't make the adjustments. It was fine before if the plate is dirty because it slowly got that way and was able to gradully make the change in your idle. If you do clean the trottle plate disconnect your battery so it will reset again. It will need to re-learn again after that. I hope this helps you and good luck.
