Thank you for all good advice.

Problem is solved.

First it was the burnt pig tail.
Then the startermotor burned.
Then it wouldn't turn over fast enough, all grounds and connectors cleaned.
Then it wouldn't start because of some stupid underdash kill switch, I hit with my knee.
And now the final problem, IDM full of water.
Replaced that with the one from my own Van, and it runs great.

A new IDM is on order

Can the old one be repaired?

 

**SOME** fellas have gotten lucky, dried out the IDM and restored functionality. If you do get it to work, I'd consider it a spare.

IDM is interchangeable across models/years, van/truck, '94.5-'03. Should be able to find a working used one from a part-out for $100-ish. Edit - oh wait, just noticed your location. Not exactly a slew of these trucks being parted out on nearby craigslists in your neck of the woods, I guess. Well, new or used, I imagine shipping's gonna hurt.

A skeptic would look at your list and think a truck like that is a piece of junk, just riddled with problems. But in fact, that list only proves just how the truck can tolerate so many looming faults and still run. It was only when they all "ganged" up together that you were able to diagnose and treat them.

 

I'm glad to hear you have it running! I don't know if the IDM can be repaired or not to be honest. I know there are some places out there that re manufacture and sell automotive computers, but they generally just get the old one back in exchange for a core charge. It would be my guess that you're probably better off just getting a new or used on than you would be having one repaired.

 

I will try to dry it out.
Noticed that the one from my van had a ground wire mounted on the bottom side, and the wire was bolted to a ground point near the headlamps.
It also had a small hole next to the ground wire, like a drain hole.
Maybe someone has dried out mine some time ago too.

There are a few of these at the breakers over here in Norway, but it's hard to get only the IDM and not purchase a complete engine.

"Madpogue" that's why my friend got the van really cheap
But he can't fix it himself, so he drops them off in my yard.
With the help from this forum, I can fix anything

Nearest garage to fix these Fords are 2.5 hours drive from here, and they only care about european fords.

Reps sent to y'all

 

Hopefully you're able to dry it out. I haven't heard of anyone who has done that but, it doesn't hurt to try. What about ordering online? Are you able to import things like that? I know customs can be a pain, but I think you could probably find one on eBay or something.

 

I order all parts needed online, usually I order directly from parts suppliers.
And I use ebay for 2nd. hand parts.

I placed the IDM in a closed room with an airdryer compressor. Hopefully that will suck all moisture out of it.
