Fiero wont start

When you first hit the key do you hear the pump fire up?  If not the first thing to do is replace the fuel pump relay.  Its just behind the air filter box.  If the car is an A/C car, you can swap the fuel pump relay and the A/C relay to test.  They are right next to each other.

If you DO hear the pump but the car won't run without spray, then replace the fuel filter.

Next up check the fuse's.  There are 2 fuses for the V6 fuel injection.  Its dumb but true.  Its a batch fire system, but there are 2 fuses one for the left bank and one for the right bank. 

After that, if it still won't start, you got me.

Yes that filter can be plugged solid with crap in the bottom of the tank from sitting that long. 

You did not mention that the car had sat that long.  It is very possible that the injectors are seized up.  The 85's used needle type pintels.  Imaging something the size of a sewing needle that needs to spray the fuel.  It can become plugged even with regular day to day use, let alone sitting for that long.  

I'll warn ya know, the last time I priced a new set of injectors, it was in the Two Thousand dollar range. I typed that out just so you know it was not a typo.  However used injectors / rebuilt ones are only $200-$300 for a set of 6.

P.S. the fuel filter is under the car, on the bottom kinda in between where the base of the passenger seat is and below the battery.  Its a large silver can with 2 threaded pipe fittings going into it.
