If the Crankshaft (Crksft) was bad, the car wouldn't run.

Take an ohmmeter and measure the resistance; It should be around 1000 +/- 200 ohms (if I remember correctly). It plugs into the Distributer Ignition Module (Menu#5) via connection labelled "2". Unseat the connection and measure between the inside and outside connector. Flex the wire and connection to see if the reading is intermittant. If solid, you can say the Crksft sensor is ok. Not seen one go bad yet!
