850 turbo not cranking over

Swapped the switch over with a spare used switch. Tested, and still showing voltage on the housing? Now she's running. Gonna reassemble and go for a test drive.

Final update (hopefully) she is running well after replacing the ignition switch and the charred ground wire. Although I still believe the starter was the root cause. My thoughts are that because the stator was so rusted on the starter, it caused internal failure, causing high amps to overheat the ignition switch causing a dead short that had to return through the charred ground wire. Thoughts? Thanks for all your direction through this challenge!

Hopefully you got it but the ignition switch should never see an real high current since all it does is trigger the solenoid, not the starter motor itself. If the solenoid was somehow shorted out it would all make sense.

Ok, drove the car for a week. No problems. Then all of a sudden she died again. Thought it was the anti theft/immobilized relay. Removed and jumped relay. Again good for a week, then died again. Any ideas?

Also, every time it stalls out, all the doors lock. Any ideas?

You still have major electrical wiring damage in your car, I think. This is just an ugly thing to deal with because it requires removing the looms, opening up,the insulation and inspecting all the wiring for melting and shorts

I think your right, but I'm pretty sure I narrowed if down to just the wiring going from the steering column to the relays under the dash. After some jiggling of said wires, she fired right up. As I squeeze the wires together, she stalls. Opened the loom again and checked all wires. Nothing showed up by visual inspection, but I did tape up several wires that had a light burn in the insulation. Drove to work no problem, but it is usually a 7 day cycle between failures. I'll keep posting if I find the smoking gun. Thanks again!

I had the exact same thing, the long plastic piece has to come off and there were about eight wires that had been pinched together causing them to arc, melt, smoke and make the car not run.

My mechanic did the soldering and insulating of the wires, the car has never run better meaning that must have been a lingering issue for years.
