I have 1997 Dodge 1500 4X4 ,died on me ,comes up with a code PO320 ignition/distributor engine speed input circuit.Your posts point to crankshaft position censor being faulty.Can you please tell me the location of that sensor and how hard it is to replace it?
Thanks

Located just off the side of the crankshaft pulley. Access should be easy. Just one mounting bolt.

Thanks TGreaseMonkey.Found it!
