There is a club in your area. It's known as NIFE. Northern Illinois Fiero Enthusiasts. Try this link http://www.fierofocus.com/ There is also another Fiero Forum known as Pennocks Fiero Forum. The url is
http://www.fiero.nl When you get to the home page, on the left side is a heading for Pennocks Discussion Forums. Click on that and you will go into sections similar to what we have here. I'm not trying to direct you away from us, but giving you some alternate information sources. I saw you when you registered earlier and was waiting for your post. Welcome to our forum.
For a car that's been sitting that long, among the things that would likely need to be tended to would be the brakes. Generally the calipers sieze due to moisture and corrosion in the piston bore. The gas usually turns to varnish, so the tank would likely need to be removed and cleaned out, as well as the fuel filter being replaced. You say the car is a 4-cylinder 4-speed. That would be an 84, not an 85. The 85 and later 4-cylinders manual equipped cars had 5-speeds. The fluid in the clutch system would likely need to be bled out, and there's a possibility that you will eventually have to replace the master and/or slave cylinder, for the same reasons as the brakes. Moisture and corrosion.
Before trying to start it, it would be best that the spark plugs be removed and a light oil be put into each cylinder. Maybe a couple of ounces in each cylinder. Marvel Mystery Oil or something similar. Don't put ATF into it because if there is any silicone in the ATF, it can foul the o2 sensor and the catalytic converter. Let the car sit for a day or so with the oil in the cylinders. Then with the car on a level surface, put it into 1st or 2nd gear. Get someone to help you give the car a little push to cause the engine to rotate just a little. This will help in case the rings or anything is stuck due to the long down time.
While the car is sitting, with the oil in the cylinders, you also want to go through the car and make sure that no little critters have built nests anywhere that could cause a fire. Get a small hand mirror, something like a lady's makeup compact, and do a very detailed inspection of the exhaust manifold area to be sure there are no nests or stray materials on them before you install the plugs and try to start it. Check inside the air filter canister and the intake tube and the breather on top of the throttle body. There is also a blower fan inside the passenger side of the trunk, at the top, behind the carpeting. It's located inside the right rear fender. Just pull the carpeting aside. Check to be sure there are no nests in there. The heater blower motor is another place they sometimes hide.
I'm assuming that it still has antifreeze in it, so don't mess with that at the moment. Getting the air out of a Fiero cooling system requires following certain steps. We can help you with that when the time comes. Drain and replace the oil, and change the filter. 10w30 should be good.
While I've been writing, I see Robbie has posted some suggestions, with a few variations to what I've said, but they're both good suggestions. Robbie's the mechanic. I tend to be quite cautious, so some of my suggestions may be a little overkill. However, I do disagree with Robbie about the ATF in the cylinders.
Hope these suggestions will get you started.
