92' Taurus engine/fuel problems

I was driving home one day and my engine died. I had forgotten about the oil gasket leak that I have. I checked the oil and I was completely empty and the coolant was out for a coupla weeks/months due to our really low temperatures in Iowa. So the engine died then the oil, engine, and battery lights came on and the power steering went out and the brakes stiffened up. I open the hood and I think I could've cooked bacon on the air intake housing block. So I let the under hood cool down and then my dad came and we filled up the coolant and and the oil. We cranked the ignition and the engine turns over but won't start.

So I get it home and spray some starter fluid in the air intake valve and it barely starts up. So I check everything out and my fuel filter looks like it was '92 stock. I switch it out and no luck. I check the fuel pressure and it is roughly 17 PSI. I call up a mechanic friend and he suggests switching the fuel pump. I do so and then then I check the fuel pressure and it's 10 PSI. I come back a day later and there is no pressure at all.

I'm at a dead end as no one can help me and I have no more leads besides a disconnected tune that connects to something to do with ignition and the air intake block. I'm gonna get some replacement tubing for it tomorrow but I don't think that could be it. Please help me out and it would be greatly appreciated. If you need any more info please let me know as I need this fixed in roughly a week. Any leads are lovely.

Quite honestly, if you drove it with no oil or coolant to the point where the engine stalled, it's not probably worth you putting much money in to. Even if you get it to start, the engine will probably be degraded enough that it will never run right. Especially if spraying starting fluid in the intake gets it to barely start and run.

If the tube you found disconnected under the hood is a vacuum line, you can fix that, but it still won't address the low fuel pressure. The underhood temperatures likely fried a few other vacuum lines under the hood as well.
