when you stop using a vehicle you have to put gas STABILIZER AT THE double dose when for a 1 year sleep. also you must put a few miles on it with this in the fuel before shutdown.

crap grows in the tank ..I suspect a plugged up filter.. with alcohol the less you use the vehicle the fuel filters require more frequent replacing.. cut open the old one hopefully it did not blow and get crap in your TB,..

I know I am assuming a lot with what you may know about these things.

since I really have no idea of your abilities or knowledge.
The reason I stated to cut open the fuel filter was for YOU to see if this filter is dirty. you ever see filters like for a furnace air filters. or even the air filter in the air box of a vehicle . well this is the same in the fuel filter. the filter media has pleats . these should look clean and not be filled with debris [DIRT]. Also the pleats should not be fractured because if the filter is with debris , the restriction can cause this filter to blow out and then the debris will foul the injector.

next is the injector connection maybe damaged or disturbed when you cleaned/sprayed it. the electrical connection may need some work.

the TB has a fuel regulator and this may also be damaged. being this old good chance these things need some work.

find someone that has some knowledge about this stuff and see if they can see whats the issue.
