I have seen a few different people have problems with the electrical lines/connections inside the plenum not properly activating the injector. You may want to see if that is the cause.

how many volts should there be?

Have you checked the timing. It could have jumped time and it will never start. Bring the number 1 piston to TDC, Check that the rotor is pointing to the number 1 plug. The Rotor should be pretty close to the # 1 wire location at the distributer cap.

how about fuel pressure, Fuel Pump Relay, Fuel Pump Regulator.

Are injectors pulsing, I do believe you can check the Injectorpulse with a Noid light. (At least that's my understanding of a NOID Light) That would tell you if the injectors are being controlled by the computer.

The problems that I have seen and heard about surrounded the electrical connection to the injector whether from corrosion or relaxing of the connector plastic.

i took back spider{fuel pressure reg,injectors}and got a new one just to be sure.same thing.i have fuel pressure.with the plenum off i can see the gas through the line,it makes it all the way to the spider fine.but when i hit the key,no fuel sprays out of the injectors at all.i have twelve volts to the spider as soon as i hit the key.im gonna go check the conecting clip real good,thats a good idea swart .ill be back.
