Geo Prizm will only run if I spray starter fluid into airbox

(1990 Geo Prizm)
in Glendale, AZ on March 10, 2015
The car turns over and runs great as long as I feed it starter fluid. I can hear the fuel pump priming so I disconnected the fuel line from the fuel rail and watched a good flow of fuel coming out while I was cranking the engine. With the key in the on position, I put a test light through the yellow wire of each injector and had constant power. The vehicle was my deceased fathers and has been sitting for a 3-4 months, There is evidence of pack rat damage in other vehicles but I have not found any damage so far in this car. My father was a mechanic and was known for jury rigging most things so it is possible he "modified" the car although not likely.

Injector power circuit should pulse the light (flash/blink) when engine is cranking!
