I've tried that. It doesn't work. Press the pedal to the floor and keep
it there, the thing revs for three or four seconds then dies. And you
smell gas. Pump the out of it for 20 seconds and you're running.

I resoldered the relay and it didn't solve the problem.

Cleaning the contacts on the coolant temperature sensor, by plugging and
unplugging it a handful of times, solved the problem. It starts right up
now.

of course - you have to let the throttle back to a more normal position
the moment it fires!!!

there no injection programming to support this action.

let's get this back into context:

you originally wrote:
"3) When the engine is hot, if you push-start the car (which doesn't
activate the starter, hence doesn't tell the PGM-FI "you're going
through a startup cycle") it always starts."

check out tegger's description of main relay operation - that'll explain
everything for you.

bottom line, if the main relay is operational, it'll start regardless.
if it's got intermittent open circuit, the "start" position will not
ground the injectors, hence the problem and the difference between the
two modes. the ecu triggers the injection cycle when the distributor
tells it to - regardless of how the crank gets to be rotated.
