This black part of my 318 ignition started smoking now I have a no start . Any ideas . Ty . Tried a few things . No luck yet .

Electronic ignition module. The smoke means it’s junk now. When you replace it get rid of the flat washers and use star washers on the bolts. It needs to be grounded.

YOur local Napa parts store or Canadia Tire still has listings or the ECU.

Hope this helps.

Did the smoke come from the ECU (the metal box) or the wiring?

Your description sounds like it came from the plug on the ECU.

It came from the plug on the ecu and also a little from the Alternator. Hopefully I didn't fry the plug and Alternator as well

I think you need to check your voltage regulator, all your connections and grounds are clean.

I will . That has been changed but maybe it's junk . Car was reading 13.6 volts while car was running at battery. Other one I have reads around 14. Maybe I should put it back on

You haven't said what car this is in.

Judging by the way and where the ECU is bolted down, it looks like this is an older car with Mopar Electronic Ignition added on.

Given that you had smoke at the alternator and at the ECU, I would say the first thing to do is look at all the wiring and connections. You may have a short from bad insulation or a bad connection. And yes, that ECU needs to be grounded better... Right now it looks like the connection to ground is dirty or rusty.

The problem may be the ECU... But if you don't address any wiring problems, you take the chance of frying any new parts.

13.6 volts sounds good. You're going to have to check as much as you can before you start throwing parts at it.

Thankyou . This is a 65 Savoy. It's a Canadian car

Apon checking wires I came to this on fire wall. Is the link in the block itself? If so where do I find . I don't think it was working because some of my primary ground harness was scorched . Inspecting all wired ignition due to this near fire .

 

[detmatt]

That’s just a junction block, the fusible link is in the wire itself.

Thankyou . So I cut out existing and replace? I'm sure it's blown . I suck at electrical. I'm learning. Was just cleaning grounds and I came to this. I believe bad grounds is part of my issue

 

[santts]

I see its quite dirty in there where fusable link goes on firewall. Does the wire burn up when it's bad? Like how do ya know ty
