I have a 99 Dodge Durango one day I got in it and it
wouldn't start so someone changed the fuel pump
my crankshaft sensor and I just got my throttle
shift sensor change the car still doing the
samething turning over but won't crank what could
Morning. I just recently had the same happen.Truck would not start. Only cranked over. Had a 'No Bus" code displayed. Problem was caused by a short in the wiring. Found frayed wires on a few Solenoid / sensor connectors located on the driver side of the Transmission. On one, the Automatic Transmission Solenoid, wires were frayed, twisted and making contact. I replaced the connector harness, taped up exposed wires on the others and now truck is up and running.
here is the ATS i changed out with a new harness. Hope info works out for you.
