    That valve barely squirted out any fuel, in my opinion. Should be shooting strong like Ron Jeremy.

    But for real. Something fuel related is going. She cranks solid from what I hear in that video. Re-check fuel pump. You should be able to clearly hear the fuel pump tuning on/priming. Should be very very easy to hear. I once did a hot-wire on GTP fuel pump and mismatched the wires and it would not start.

    Is there fuel in the car? That's another question (been there myself).... There's also the fuel filter. Hows that looking? Last time it was replaced. Might by gunk lodged in the filter and just moving around causing it to flow/not flow. Any leaks in the fuel lines? They are usually rusted out by now in these cars.

    Go to AutoZone, rent the fuel pressure tester. It is free to rent. And test pressure and valve. Seems weak to me.

    key needs to be turned to run to make new pressure. the pump primes for a few seconds sprays fuel via the injectors, then turns off, dont come back on till the engine fires up.
