1989 Jeep YJ 6 cyl Four Wheel Drive Manual 183957 miles

I have a 1989 Jeep YJ. 4.2 L with Mopar multipoint fuel injection & electronic ignition. Ran normally when I parked it a couple of weeks ago. Now cranks over normally but won't start. I'm getting fuel to fuel rail with good pressure. Spark plugs get fire. I unplugged wire from fuel injector solenoid & get 12 volts with key on & during cranking. Any ideas?
