Yes this is the same car that I broke a plug in and successfully extracted it. It starts right up - drive it around, turn it off, come back 15 or so minutes later and it will not start. It just turns over and acts like there is no spark and it floods. Wait about an hour and she starts right up! I put in new plugs, crankshaft position sensor and ignition control module. The only parts left to try are the two coil packs. I don't know anything about this type ignition system, therefore I don't know what the peculiarities are. Question: Would the coil packs cure this issue or is there something else that could be the problem.
My thought is that when the engine gets hot it cause some part to misbehave (so to speak) and I don't know which ones.
Typically when you say "My thought is that when the engine gets hot it cause some part to misbehave (so to speak) and I don't know which ones." yes,its the ignition modual and Pickup, both are replaced at the same time.But yes, you are correct, there are quite a few posibilities,No money lost, it pays for its self, the first 2 months you start the car.
I've now changed all the ignition parts. Coils, plugs and wires, ignition control module and crank sensor. Plus I've put dielectric on the shield and contacts. The Duke starts and drives, turn it off and try to start it in 15+ mins, it turns over and gives a little cough and doesn't start. I do smell a thick presents of gas in a flooded throttle body. The Duke will start about an hour later. Any ideas out there?
1) Put a timing light on it, to see if it's getting spark during the "no start" episodes. I'm guessing it does get spark. But it doesn't hurt to check.
2) After you shut it off, open the air filter box and stuff something in the throttle body opening that will soak up gas (like a piece of cloth, or some cotton balls, or something). Make sure the stuff is under the fuel injector. Wait 15 minutes (don't start the engine, and don't touch the throttle), then pull the rag/cotton/whatever out, and check to see if it's wet with gas. If it is, then your fuel injector is leaking, and that's what is flooding the engine.
I did check the spark and it gets it. I put a new ground from the "Brick" to the engine. Since it does reeks of gas when I try a restart, I'm going to test the injector for leakage. Oh, just noticed, on a fresh cold start, it fires up and idles for about 3 mins and then the "check engine" light comes on, therefore it's time to check the codes.
I'm getting codes 42 Electronic spark timing and 15 Coolant sensor. I have all new parts in the ignition as stated previously. I even installed another injector. It runs smooth at first start but still will not fire up 15 mins or so after it's been sitting. It will fire up after about an hour. Any suggestions?

I pulled the "Birck" and had the "New Ignition Control Module" tested at Advanced Auto and it failed the testing (3 times)!!! As soon as the new one comes in I will have it tested before installing it. I will post the results as soon as the replacement Brick is reinstalled. All the input on this Fiero issue has been very helpful.

Missing shield on this version will cause problem... If missing, find/make another. See my Cave, DIS Ignition
Wrapping up the ignition problem, I hope! The NEW ICM that I had purchased in the beginning of this mess was bad. Had it checked out at Advanced Auto and it failed. The company I bought it from replaced it, no charge, checked it before installation, it passed, sweet! Installed it, ran it, let it sit for 15 or so minutes, it started, drove it 12 miles, parked it, started it 15 mins later and she fired up! Time to move on to other issues... Thanks to all that contributed to the solution. MrRich out.
