Car will not start issue

I can spray starter fluid into the intake and it fires right up. Once the spray stops so does the motor. Fuel pressure is 45ish. Injector light shows its not getting a pulse. Changed out the computer and still have the same problem. Anyone have any insite to my problem?

Car is a 1990 IROC with an automatic and 350.

I think I may have a similar problem, but no one has given me any insight as to what it could possibly be. I have changed relays, fuel pump, fuel filter, coil, cap, rotor, even put a fresh battery in. Fires up, runs then shuts off. If I spray carb cleaner in it will run a little longer, but then runs real rough and shuts down. If I make any headway I will let you know. Mine is a 1991 350 TPI GTA. Howard.

Just to follow up I figured out the problem. #5 injector was shorted out. Measured 0.9 ohms. Changed it out and the beast ROARS again!
