What do I check next?

Asked by Apr 26, 2015 at 10:21 AM about the 1994 Chevrolet Cavalier Z24 Coupe

Question type: Maintenance & Repair

I can get the car to run(not well) by spraying
gas into s vacuum port so there is no
ignition problem but the injectors aren't
operating. I have swapped the crankshaft
position sensor with a known good one and
same result so that is not the problem. One
question is, is there supposed to be voltage
going to the crank sensor? I have checked
continuity through the wires but there is no
voltage through either wire with ignition in
run position our in cranking position. I have
checked injector wiring with noid lights, and
they're not getting signal. There is voltage
getting to the injectors but no flash with
noid light. I have checked fuel pressure
already(45 psi). WHAT DO I TRY NEXT?  
Very frustrated.
