Today I was changing the spark plugs in my Ranger & found the plastic cover on the harness that goes down to the crank sensor melted against the exhaust manifold. I stripped back the melted plastic cover to find this. One of the wires has about a 1/2" section of the wire bare, the second wire appears ok, & the third one is completely bare as far as I remove the plastic cover. I removed the plastic cover the rest of the way to the sensor plug connector & there are only 2 wires coming out of the plug & the bare wire stops about 2" short of the sensor plug, & the sensor plug shows no signs of being melted. I have no idea what the bare wire is. I also checked on Rock Auto for this sensor plug & it is only 2 wires. Does anyone have a wiring diagram for a 2000 with a 4.0 that could check the wires going to the crank sensor?. I am going to tape up the 1/2" section that is bare & see if the truck starts.
