Engine shutting down while driving

[mo.eagles]

This is kind of old but I'm hoping to get more info. Nightpath, did the solenoid solve the problem? I had the same problem with the wagon I got in Arkansas . It would just shut off but restart with no problem. Running down the hiway and die . Put it in neutral at 60 and it would restart and go. Then it ran great with no issues for 2 years .Now it's acting up again. Not all the time ,maybe once a week, but it is aggravating.

I fixed mine 100% by doing a drivetrain swap

Mine was the crap solenoid causing issues, and a crap battery. It was getting voltage spikes or none at all, and was killing the car repeatedly after 15 minutes of driving.

Hi! I have an ‘84 and it’s been doing a lot of the same things that I’m reading on here and I’m really hoping someone has a solution for me. It randomly kills at the weirdest times. I could drive 30min and it’d be fine or it would kill every block. I’ve replaced the: distributer, fuel filter, coil, starter, spark plugs, caps and rotors, abt 2yrs ago we did wires, and we even have a new battery in it. None of these have worked tho, she still kills randomly and Idk what I’m missing. Help! XD

Might be the icu? It is mounted under the solenoid on the left fender. I replaced mine about 10-11 years ago. The wires come out upwards, it puts a bit of a strain on them and they can crack. Mine were. Finally replaced all of it with a hei.
I bought my old icu from rock auto and last I checked they still had them.

So many things it can be. (With one of mine, it was the stock coil)
Can you describe:
- the weather when this happens (wet/dry, temp)
- how does it fail: sputters, rpm falls off to dead, or suddenly nothing from running fine, etc.

First thing I'd check is all of the wires to/from the starting solenoid, ignition module, distributor and coil.

I'm a major fan of the GM ignition module as a replacement. You supply it with full voltage (instead of the stock reduced voltage through the ballast resistor) and it manages the current to the coil if needed.

You can also upgrade to a stronger coil, but will need to upgrade the distributor cap and wires to handle the higher spark voltage.

Do check the Eaglepedia for a wealth of information
