I have a 1993 Toyota pickup 2.5L DLX reg cab 4x4. Recently replaced the clutch and the wiring that comes from the O2 sensor laid on the muffler and is now burnt. Unfortunately the wires that are burnt are above the plug for the sensor so replacing the sensor wire would not help. The wires that are burnt are still together but copper is showing, there are four wires. One looks like it's braided. Since finding this out the truck will not start. It will crank over but not run. How do I fix the wiring for this sensor area? I have looked at all the wire from sensor to front of truck. Looks like one whole piece. Any ideas? Please text or call with info please 540-451-1662
