Just watched your video. Green shroud. Looks like a US 911S with a 2.7 to me.
If you have to lift the air plate to get the injectors to squeal and then it runs, the fuel plunger is probably sticking/gummed up and not moving freely (enough). Which means the pump won't be running just on vacuum, so the car will die quickly (eg when it uses up the fuel it got from you lifting the plate).
You could try disconnecting the safety switch on the AFM (another first for 1977) to get the pump to run all the time when the key is "On". Which might mean that then it'll actually run.
Also, if the plunger moves around a bit in fresh fuel, it could well loosen up enough on its own after a little while - and avoid the need to strip down the fuel distributor. Which you're not supposed to do, although many have successfully. They're made to extremely fine tolerances...

LOL - what, someone put a boost gauge in the dash? Missed that...
OK, read your earlier post:

Some boost gauges only read positive manifold pressure. Some read both positive pressure and vacuum - so long as they're connected to a port under the throttle plate. For the old-school antisocial light-switch turbos, it's a useful warning of boost onset in low-traction conditions. If your 3DLZ doesn't also make a sound like an air-raid siren spooling up, that is...
Combined vacuum/boost gauges read something when cranking or running - anything that made vacuum.
Vacuum gauges are also useful on N/A cars, and some came with them from the factory - 944s & 928s, for a start. Think many Subies had/have them too. Tried to remember if the one in my 5/10 was factory or aftermarket, but it's been too long...
