When I hear of flashing dash lights, the first thing I think of is a defective alternator. When you replaced the crank position sensor, you might have caused an electrical problem in the alternator or regulator if you did it without first disconnecting the battery. Go to a car parts store and have the alternator and battery checked, probably free.
