I had the dreaded wiring harness go bad on me.
I have it replaced, but the engine still stalls after coldstart within a minute or so.
I expect that the ECU might be failing or has failed due to wiring shorts.
Now: Can it be repaired?

I do have an ECU for a '93 2.8l eng from the junkyard. Could I run this one in my 3.2?
Might not be perfect but could I even try?

I think I have to rewire the trottle body actuator yet.
I hope someone can answer me soon. Thanks.

 

Check OVP relay part#.
Also, check codes @ pin 8 & 14

 

Thanks, could you tell me how I can chech the codes?

 

You build a little LED tool.

Simple, cheap device.

Make the tool and I will run you thru the process.

 

Arthur, mine has a push button and led build in . do I just need a jumper wire then?

 

The built-in LED/SW will only address Emmisions fault codes stored in the N/59 DM.
[CE lamp activation module]

You want to get to the actual Engine Management/ HFM/SFI and EA/CC control modules.

That takes the tool and a different pin to activate the retrieve flash code format.

Here are those codes

Ok, thanks. I'll whip something up and will be back for more advice.
