this should help

 

[buckbuick]

crank sensor was covered in oil,cleaned it up and ses light went away,does the crank sensor have anything to do with the codes i supplied or did i just get lucky for now.

Disconnect the ECM power at the battery for 30 seconds..orange wire.. reconnect and see what you get. Don't see a dirty crank sensor setting those codes.
