Re: wiring harness

If the wiring harness got hot or smoked you more than likely have a grounded wire in it. you can test for grounds with an ohm meter on the wires under the valve cover by reading the pins to ground. the outboard pins on each end of the valve cover go to the glow plugs. They will read a low resistance of about 1 to 2 ohms if they are good and not open, a reading of zero ohms would indicate a short to ground. The inner pins on the connector go to the injector coils. Check them for a reading of zero ohms to see if they are grounded.
They wiring under the valve cover can get damaged and might have a ground.
as far as the engine running with all 4 cyclenders on an engine being disconnected, I don't think it would run because of the great cyclinder pressures the engine has to overcome in the dead cyclinders. It might run with only two cyclinders disconnected, but really crappy. If it was me, where you saw the smoke is where I would start looking.

Good luck
Jim

94, 95, 96 PSD's are known for melting the wiring harness, I would reccomend replacing Both valve cover gaskets and all 4 under valve cover wiring harnesses, You can get kits to fix the engine wiring harness, or you can buy a new one. This is pretty expensive, but I have fixed just one side before and it came back later with the other side melted, so i replace all of it at the same time. Yes it will run with one the connectors unplugged. They will run on 6 cyl and on 4 cyl just not very well as can imagine. I have also heard of this wiping out the IDM (injector driver module) it's on the drivers side fender. You will need to fix the harness first to see if the IDM is ok.
