Default Clogged Injectors?

My '87 2.3L has been stored for 4 yrs. I had run it at several month intervals to keep the batt up and engine oiled. In the last 6 mo. my wifes surgery has kept me too busy... Now the Ranger is no start. The engine fires on starter fluid so I suspect a fuel problem. Here's where I am: Fuel pressure is 38-40 psi. Engine spark timing is 10deg BTC cranking (default is 10 BTC, I think). Engine will run with fuel dribbled into the airhorn - I've actually run it for 15 min this way. Injector elect. test points show all coils getting pulsed: Per my Fluke 73 DMM the coil Voltage drops from 12V to .9V for greater that 1 millisecond, then flys back to 32V. (implies coils not shorted or open). Am I missing something? Is it time to pull the injectors?

can you get to the fuel pump? pump sounds like its frozen up and if you can get to it and tap on it with something that should free it up

^^Could be the pump in the tank is clogged, try the old fashioned bang on the tank and start it

I've got good flow from the rail @ the schrader valve. Pressure is also good, but nothing coming out the injectors.
