I really need help.
My 86 SE is still dying engine just cuts out. I can get it started again
but it takes some time.
What I have replaced.
1. Plugs and wires ( Three years a go when I got the car)
2. Coil ( with plugs replaced with MSD)
3. Distributor (Richporter two years ago)
4. IAC ( two years ago)
5. o2 sensor ( two years ago)
6. Fuel Pump and relay (this summer)
I did have a problem with the ICM that came with the distributor
car would die. Start right back up and then die again a little down the
road. Put the original ICM back in and it has run fine for two years
until I got it out of storage this year.
Replaced the ICM (BWD) and I had a week of good running the it died
again. Thought I was having problems fuel pump problems so I replaced that.
Died again but would restart if I turn the car off and restarted it. Went to change the
ICM back to the original GM one and found the plug in the distributor seamed
real loose I tightened up the plug and the car has worked for two more weeks.
Died again, wouldn't restart. Put the BWD ICM in messed with the plug and it
started right up. About 15 minuets Into the trip home die again was able to get it
started again and get it home after it died three more times.
Now I lost not sure were to go form here.
At the point where I feel like selling it and getting a Honda I can't keep messing with this
its my daily driver now that my Durango met its fate with a tree this winter

The ICM is heating up and failing on you. Some ICMs are poorly made and bad when they are new...but many fail when they get hot. You can have it tested at some auto parts stores, but my suggestion would be to ditch the BWD brand and get a Delco ICM...some are still available on e-bay for not a lot of money. The connectors could also be causing trouble when hot....so clean them up.

Keep the faith! Fieros CAN be dependable....carry a spare ICM and a small screwdriver and you can get yourself home if it happens again.

What Gall757 said and make sure you use some heat sink paste with it (preferably stuff you can buy at Radio Shack or other).

Ya, I always carried a spare with tools. They will fail anytime. Ive had them run perfect for a 400 mile trip, then wouldnt start. I buy aftermarket ones myself, because theyre substantially cheaper and just as reliable. I paid $80+ dollars for an OEM Delco one that lasted all of a week or two. The dealer dont give refunds or exhanges on electrical parts. Autozone $22 got replaced by them 3 times for free. One Autozone one lasted almost 3 years/ 40,000 miles.
