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

Re: fuel problem no start on 89 4.3
Check you fuse panel for a blowed fuse.
Will it start on a snort of carb cleaner? Does it have spark to spark plugs?

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