Chevrolet Repair: Fuel, fuel sending unit, fuel injector

Question
Ok, I have a 1992 S-10 Reg Cab Long Box. 4.3 Liter V-6, Manual Transmission. I have invested 3 weeks of time and several hundred dollars, to replace the Plugs and Plug wires, fuel filter, fuel pump and fuel sending unit....Currently the only way the truck starts is with a blast of starting fluid...Any ideas from anyone, please help

Answer
hmm every try fuel injector cleaner or carb cleaner? sounds like the gas isnt getting misted in there. try a higher grade gas and injector cleaner and then after that check to make sure its geting the fuel up there. but i think it could be the fuel is dribbleing in there and starting fluid is thin enough to ignite it and so it runs... but do go quote me yet, i might be dead wrong. so try it and see, at least it a direction you can go to.
