Engine Will Not Start and on the off chance it does shuts off when shifting gears and/or hitting gas pedal.

After first heavy rain of the season our Van has died on us. Moving on.
Checked Spark Plugs, (have spark)
Replaced Crank Sensor
Replaced Distributor
Replaced MAF

Sprayed Ether into engine, tried to start, NOTHING!
I am smart but never learned about vehicles, my step dad is doing all the work but is at a loss. I have read around 100 Q and A on here and this is what I am reading

Spark + Pressure + Fuel + Air = Fire

Makes sense, so Fuel Pump (60psi) required, no way to test pressure atm but where you test shoots out gas.
Fuel Injector Issues?

We are currently confused as to how you can spray Ether into an engine via the air flow, turn the key and nothing happens.

Symptoms leading up: I was shopping, on the way to the store it didn't start first 10 tries or so, finally came on, switched to drive hit gas barely had any acceleration BARELY. About 7 blocks later it died at the light. 20 start attempts later I LIMPED into the store, went shopping, 15 minutes later back in van. 15 attempts to start, switch gear dies. 25 attempts to start, switch gear dies. Eventually I turtle d 70 feet off 500 attempts and 7 starts and then it dies. First thought was *its not getting any gas*.

We are trying to fix this ourselves as any other option will get us foreclosed on or taking showers at the YMCA. Any and all suggestions would be appreciated.
