How long has the van been running rich before you found the melted wires? You could have a plugged cat or bad MAP sensor. This is only a guess, but I can't see the problem you are having. Try removing the o2 sensor, but leave them plug into the harness and start the engine. This way the ck engine won't come. If the exhaust is plugged, the engine will use the o2 sensor port to let the exhaust out. If you are working on the van at home and you are still having problems. I would recommend to have the pro's to look at it.
