fuel problem no start on 89 4.3

My 4.3 S-10 truck wont start. ran fin before although would fire later then usual since i had a fuel pump professionally installed. Maybe 200 miles ago. wont fire at all now. got it to fire with ether. fuel pump sounds good and I removed one end of filter to make sure fuel gets through. Took apart throttle body and fuel is there too but doesnt come out either injector. is there a module or something I should replace? any help is greatly appreciated. Not sure how to check codes. Dont have a reader

Check you fuse panel for a blowed fuse.
Will it start on a snort of carb cleaner?
Does it have spark to spark plugs?

has spark as it fires with some ether

will try carb cleaner

checked fuses none blown but not sure if injector fuse under hood maybe

Make sure you have fuel pressure.
Check injector 12 volt feed side.
Check for injector pulse with a injector test noid light.
