[T3] 73 Type 3 ign switch.

[Jim Adney]

I usually find that I need to prime the fuel ring for 10-15 seconds, or just long 
enough to hear the air stop bubbling up in the gas tank. It can be helpful to 
pump the pedal a couple times while priming, to clear air out of the branches 
that run to each injector.

After that, I find that my '73 AT starts almost instantly.

I don't know how far off the run position of the ignition switch it should 
continue to run. I don't recommend doing that, because that will cause it to 
arc and erode away the switch contacts.
