I would put some Seafoam injector cleaner in the tank.
If you haven't replaced the fuel filter do that, $10
And put some fresh gas in the intake, start engine and try to keep it running at 1,500-2,000RPMs
Just keep manually adding gas to intake, pain, but injectors will start to work again if the rail isn't clogged.
You know what that gas looked like in the tank, well that is what it looked like in the fuel rail and inside the injectors, it will take a bit of driving and seafoam in the tank each time to clean them out.
When you were first going to get it back up and running I would have vacuumed open the fuel pressure regulator and cycled the new gas up to there, but that is past.
