I have a 88 Fiero GT V6 that has sat for over a year without starting. I put in 5 gallons of gas, and used starting fluid. Starts, but only keeps running while fuel is poured into intake. I suspect water condensation in tank. Can I disconnect the fuel filter and run the fuel pump to remove water from tank and line? What about the injectors?

Change The Fuel Pump & Strainer As The Strainer Is Pluged With Varnish.

1) Running fuel pump to remove water from tank will likely not empty it all, but it might help. Will still be some liquid in bottom of tank.

2) More than likely, the gas has gummed up and is no good, While your draining of the tank will help, may still need to change the fuel filter and clean the injectors. The ability to keep engine running while pouring into the intake is a good sign, but mayfind that more parts need to be cleaned and replaced prior to solving the problem.

When I put another 2.8L short block in my Fiero that hadn't run in years, the injectors were actually gummed up and it took about 3 minutes for enough of them to free up for the engine to run on it's own. A few minutes with some new gas going through the rail was all it took to get the engine back to life after it's long period of inactivity.
