Ok, i drive an 88 couple, with a 2.5l engine. it was running fine today, then, unexplicably, I lost alot of power, and could barely chug along. I get to a place where i can stop, open up the decklid and see smoke, but cant tell where it is. because I was parked in a bad spot, I move my car less then 100 feet, and opwen the decklid again, only to see the damn DIS ON FIRE!!! I quickley put the fire out, now i dont know what the heck to do. I'm 90% sure it was the ignition setup (stock), but it was dark and the intake manifold was in the way, I had a hard time seeing. Does this happen to anyone else? any ideas what caused it? my only guess is because it was raining today maybe something shorted out. will I need to check the crankshaft? or should I be fine with replacing the DIS?

Avery sorry to hear of the fire but it sounds like your Fiero at least survived the ordeal. A fire in the Fiero engine compartment can originate from many sources but I've never heard of the coil pack going up in flames. I think that you need to do a very close inspection to locate the precise origin of the fire and insure that it is fixed properly before driving the car again. Most often, trapped dry leaves, parking over high grass,leaky hoses or lines, electrical shorts and /or a glowing hot exhaust manifold will trigger a fire. Since there are many possible causes, I don't believe that we can help you on the forum but if it will make you feel better; you are not the first to expereince a Fiero fire. Just ask Phil from VA. I think that he lost four or five Fieros this way and I knicknamed him "The Torch".
I think the major part of the problem, regarding nearly all Fiero Fires, is directly related to the owner not replacing the 'age-old' equipment before a problem arises. These cars have plenty of years on them, if you're still running the parts the car was built with, you can expect things to get real exciting. The other part of the equation is repairs that were not done properly. As far as leaves go, that's car maintaince that every Fiero owner should be advised of.

I replaced the PIM [Pimary ignition module, was burned up, literally.] and both coil packs, and my car has been running fine since. And just a word of advice, go with A/C Delco parts on this one. And if you have not done so recently it would hurt to replace your plugs, making sure they are gapped right and wires as well.
Hope that helped.

Fortunately, or unfortunately all my fires have been on V6's and started mostly from debris or an oil leak on the side nearest the firewall.
The coils on the DIS are notorious for leaking spark when dirty or wet, especially if the plug wires are questionable. It's easier for the spark to travel the path of least resistance....like the coil itself or wiring or oily or dirty motor. I'd spray down the coils with a cleaner and clean the entire engine, then replace the wires with PREMIUM wires. Good luck.

the wires and plugs are new (<500 mi anyway) I did a tune up just before winter. I replaced the DIS with a spare I had and sure enough, the old one was TOAST. lower coil pack is melted all to hell. Put in the spare, and she runs fine, no flare up. thanks for everyones help

Had an 87 4 cyl do the same thing, the water hose that connects under the intake manifold dripped anti-freeze onto the coil packs igniting engine compartment. Replaced the plastic connector, the wiring harness and coil packs and drove it another 2 years.

I seem to recall a thread or two about the O-ring underneath the distributor leaking and oil getting places where it's not healthy for it to be... might this have contributed to your problem?
I might be misremembering, but I figured I'd offer it as a thought.

CUTE ROB........LOL. ACTUALLY I THINK IT WAS 5.........BUT I'M ON A ROLL NOW. IT'S BEEN A YEAR SINCE I TORCHED ONE.........YEA!!!!!!!
I AM EXTREMELY CAREFUL NOW TO BE SURE OF NO OIL LEAKS OR BUILD UP OF LEAVES OR DEBRIS..........
Besides..........This car and I made an agreement. I'd keep it nice and make it all pretty and maybe put a new engine in it and in agreement it wouldn't catch fire...........LOL. God the things I do to justify myself.......LOL.
