I had a similar problem with my 87 and 88 GT's. I replaced the ENTIRE ignition system from the distributor out to the spark plugs. It turned out that the problem was the cold start injector sensor was bad AND the plastic connector was brittle and falling apart. I would suggest checking your cold start injector sensor as well as your temp fan switch. Both of these sensors are located on the top right hand side of the engine right behind the thermostat housing and under all of those plastic vacum hoses...if you have the V6 engine. You could even start by pressing the connector down on the sensor just to make sure that it didn't come lose. That actually worked for me but after the car started I decied to replace them anyway.
I would also check the ignition module. These commonly fail in V6 Fiero's. They are bolted to the top of the distributor right under the cap.
Hope this helps to solver your problem. Fiero's Rock! I've got 5 of them.

The primary ignition system is ignition pick up coil and module.thy are both in distributor.check for 12 v at ignition coil positive when ign switch is on . if not you have wiring problem from switch to ciol
if o k have someone crank the engine and check the negative side of coil with a test light.if it does not flashes replace distributor.
