2002 Duarango with "no bus" code on odometer. No spark (won't start on ether). No codes on rented Auto Zone scanner. Crank sensor was shorted, bringing down 5-volt PCM system. Replaced sensor and now have 5 volts in PCM circuit, however still have no bus code and will not start. Does PCM system have a fuse and can it be a problem since there are 5 volts? Does the PCM code have to be deleted from computer for car to run and if so how to do it? Have had battery disconnected with no effect.
