A caravan 3.3L one day will not Crank, the Battery is Good, All fuses Good,neutral Safety Switch is good, Starter Is good, Scanner will NOT Communicate with PCM Cannot run ATM tests with scan tool, BCM Communicates with scan tool ok. Fuel Pump runs, Security light on,All lights work key on. Wont' make a difference with battey charger connected. Disconnected Battery, No Change. PCM Will NOT do automatic VIN entry with the key ON. Engine Will turn over if I "jump" the Starter Relay but just Cranks.
