Not being as well versed as in Diesels or Digifant, CIS has issues with the ait control plate that can become "Sticky", and I have heard of similar issues with it when this happens. The issue is that Fuel that is allowed to evaporate in a system can lacquer things up, that you have tun new gas in it can cause things to break free and clog up other things.
Is this an early 84, or 84.5? as the difference is that the 84 had a 10 gallon tank and a full sized spare tire. Where as the 84.5 has a 13 gallon tank and a space saver spare tire.
Why? because the 84.5 has 3 fuel pump, one external and one internal? So let me ask if the fuel pumps whine? that is can you hear them?
The issues are that when the in-tank pump becomes fouled, it can cause the fuel form the tank to not be delivered to the Primary fuel pump effectively starving the primary so it has to work harder and whines about it. The in-tank pump can go bad, and or the connection hose that holds the fuel pump to the sending unit can break or hole. So if you have an 84.5 you may want to pull the inspection plate and remove the sending unit to take a look inside your tank.
not only to validate that your pump is in good shape, but to see if there is any rust or things in your tank.
WARNING you have to have 3/4 or less of fuel in the tank to pull the sender, and you have to disconnect the battery....
in the FAQ's or DIY sections I have a How do I do that there.
