Engine won't start after recharging battery. 90 f-150 5.0 4x4 automatic.

What is your question?

I sprayed starting fluid in it and it started and died so I have spark. So it's a gas problem thank is 1\2 full. I checked the emergency shut off switch its good. It started and ran fine before battery when dead. I put it on charger over night next morning the engine turned over fine never tried to start. I checked the fuses in side the cab their good. I've turned the key off and on many times to see if the computer needed to reboot still nothing. What next???
