If you're finding it difficult to service/repair your car, get one of those online manuals. You'll not have to wait for others to answer, or rely on mechanics and all. Plus I know a website that has very good manuals online, without expiry

i.e. for lifetime.

Found this info.
Use a magic marker or something, mark around all the hinges before taking anything loose so you can get them back in the same place. Use two people, one on each side of the hood.

this is done the same way as bleeding the brakes. make sure the clutch cylinder does not run out of brake fluid. the pedal should feel firm all the way through its travel and not soft.

Torque converter solenoid. Or maybe just the wiring to it. Another common problem.

The injectors need to be tested for pulses between the two wires (not to ground or +12) with the engine turning. With it still, you will get almost the same reading (only noticeable if you use a meer) from both wires since the injector has a coil of wire between the two terminals. The electronics may float between ground or +12 on the wires depending if they are powered up or not.

Do you have the appropriate pressure at the fuel rail? A V6 takes a lot more pressure than the 4 cylinder cars.

Holy C**p. Kind of beyond the scope of this forum, dude. You need to search for a fiero forum, as I'm sure someone else has done this.

Sadly your car is very old. But the good news is scap yards keep so man parts off any type of old cars .. Check with a mechanic first for the problem first make sure what it is !! and then if it needs changing call around. Could be a wire problem to the fuse could be anything check it out first.

If you mean Idle Air Control, it's on the throttle body below the throttle position sensor. I think it's a deep, 28mm socket that fits over it, or you can use a big adjustable pliers or wrench. Read the instructions on the new one. Don't loose the pintle! Don't turn the ignition on with the IAC hooked up but not in place. The pintle will go flying out.

Have same car, same problems, easy solutions.

Getting into gear has been improved by putting in neutral with engine running to warm up fluid. The Fiero has very little room in the pedal area. I'm shifting a lot better with smaller shoes.

The problem with starting may well be related to the same issue. There is a neutral safety starting switch. If you're not pressing hard enough on the clutch - starter won't run. According to the Fierostore.com stock clutch pedals tend to bend. They sell a stronger replacement.

My Fiero has been starting just fine the last few days. The last time it didn't I was wearing boots.

I've almost always been able to get it to start using a booster battery, but Walmart's tester indicates that the battery and charging system are fine. It recommends tightening connections. I did this, but still had problems for a while.
