So the guy I bought my 86 gt from lied about everything on this car. I'm still gonna fix the whole car anyway but I wanna know what parts will need replaced on a fiero that's been sitting in arizona for 4 years 😑 so far I got. All the gaskets, water pump, timing chain, oil pump and pick up tube, new overflow Reservoir, motor and transmission mounts, cradle bushings, new belts, tierods and ball joints, sparkplugs, fuel pump, 15lb fuel injectors and my brakes and rotors.

you should clean out the gas tank.old gas turns to sludge.

Hailey, I had to go back to your first post on this forum, did you decide to keep the stock engine and rebuild it? Back then, you mentioned a 3800 swap.

I'm starting college this fall and needed a running car for it so I bought a new 2.8 v6

You might want to check the wheel hubs and bearings as well, typically sitting in one place for a long time doesn't fair well.

Check everything that you can, and can think of, but you don't have to completely fix every little issue immediately, get it to the point where you can safely drive it, just a basic check on things like tie rods and ball joints and bearings to make sure they won't fall off on you, but don't have to be perfect, get it on the road, enjoy it, issues will arise and you can fix them then, and in the meantime you're getting paid back in enjoyment for your financial input, after a while, depending on your budget and time, you will hopefully get ahead of "repairs", where you don't encounter many new, unexpected problems, and where additional money goes into the nice parts like interior, engine swaps, more power, upgrades, etc. if you go all out and replace everything with a little issue (but still drivable) now, you'll end up going back over those parts of the car with upgrades later, an example is that I bought (for no reason at all) Rodney's slave cylinder, which I can't use now because I changed out the transmission for a 5 speed with an integrated hydraulic throwout bearing, I don't regret buying it, nor anything from Rodney, but it was technically unnecessary, as my aftermarket upgrades later replaced the very parts I had bought new to replace original things. I bought Rodney's EGR tube, and now I'm not using that because I can't use EGR with megasquirt, etc. etc. only replace what you definitely need to, that will save budget to get better parts when the slightly problematic ones get worse or fail, or allow upgrades later on that you might not have envisioned, without the regret of replacing a perfectly good, new part for no reason at all.

A very important thing to check, actually just clean out, is debris which entered your heater box. Fires on more than a few Fieros have started there.

The perspective I have now, and the perspective I had then when I was your age are totally different... so I'll try to view it from your perspective. When I would get a car of questionable quality and condition... and I didn't have tons of money to throw at it. My first goal was to get it running, give it a basic tune-up, and just start diagnosing things from there.

So, the first question I'd ask is... does the car run?


If the car sat for a very long time, I'm guessing that all the rubber is probably shot, which includes the fuel lines. Safety is really the most important thing here, so I'd want to swap out the rubber fuel lines, which ideally requires dropping the tank, cleaning it out, and replacing the fuel pump while you're at it. I'd go with all new FUEL-specific lines to replace the ones for the pressure and return, as well as for the fuel evaporative canister. Next, I'd replace the fuel filter, and then put all new fuel in the tank.

Then... in this order:

- Change the oil and filter.
- Check the coolant... does it have any, is it in good shape?
- Get a new good battery (you're going to be cranking a lot)
- Try to start it.


If the car starts... awesome... at that point, if it runs like crap (but at least runs), and you hear no mechanical damage, then everything can be easily fixed... and work from there.

Before you actually start driving it though, you'll likely want to change out all the coolant hoses. Arizona is brutal on rubber hoses... and those things will be so dry rotten. Make sure you "burp" the cooling system.

You replaced those items because they were bad, or because the car had been sitting for four years?

Mix of both I checked them out first
