Don, I don't know your wiring on the Iron Duke, but when my V6 quit running it turned out to be the power wire from the ECM under the center counsel at the connection between the seats about 4 inches from the connector, you could not see a break in the wire until i started probing it with a straight pin, spliced in new wire and WALA, that was about 7 months ago and no problem since

It's back to the "No radio, no lights, no dome light, no emergency flasher" plus no fuel coming out of the injector!

I am suspecting a major foul-up in the electrical system or bad ECM but don't know how to confirm a bad ECM.

on the FP connector I get no +12 V on green or tan/white when turning on the ignition to prime the pump. I know it should send power for about 2-3 seconds. The orange however does have power.


I am getting too confused now. I have taken notes on everything I have tried so I don't back-track unnecessarily but am stuck and giving up hope.

I could really use some guidance here. How can I confirm a bad ECM. Various posts on other forums haven't helped

Disconnect the battery NOW!!!
Pour water on it to cool it down ASAP!

Do not attempt to get too close to it. It will be releasing a lot of explosive gas now.
You can try to search for the obvious electrical short after it cools. Much later.

Possibly the alternator....but later.
Disconnect now!

The Don

What up? You still here? Hope so! A hot battery is no fun. Seen 'em blow up...not pretty.
Seen people that were near when they blew up...not pretty.

If there is no electrical short in the system, built up sulphates in the battery can short out cells.
If enough of them short together the battery will self destruct.
There is no fix. Just get a new battery.
Much better, cheaper and easier than getting a new The Don!

might have been too late disconnecting the battery, now nothing is working anymore - she's dead - and most likely going to stay dead until I get the new ECM in the mail and maybe somebody to help me figure out where she has wires crossed

I was thinking it might be a fusible link that has failed based on your initial symptoms.  Now, it sounds like something is shorted out.  Try disconnecting the cooling fan connector at the motor.  If the cooling fan shorts out and blows a fusible link, the electrical system will go haywire.

The harness plugs into the cooling fan motor.  When my 87 had the same symptoms, the cooling fan motor shorted, blowing a fusible link and the car shut down.  Only thing that worked was the interior lights.

I'm glad you're alright.
You sure know how to startle the fertilizer out of somebody.

There's a link somewhere on this site that has ~all the factory
manuals. Fierofool probably knows right off the top of his head.

The fusible link on mine was located at the junction block near the battery.  The 84 is located on the back of the cockpit, and the wiring is different on the 84's.  There's also one down near the starter.  If it is a fusible link, then you've got something that's grounded out pretty good.  I'm not much with electric problems is why I've not made many suggestions.  I don't want to get you off on the wrong track.
