    Check the resistance of the key pellet and document it. use a dvm on the pelet built into the key
    2. Disconnect the key cylinder wiring at the base of the column and install an ohmmeter across the terminals on the steering column side of the connector. 
    3. Insert the key and check for the same resistance value as documented in the previous key test. 
    4. If the resistance values do not match, there is a problem in the key cylinder or the wiring running through the steering column. 
    5. If the resistance is the same, rotate the key to the crank position and tilt the column up and down while monitoring the resistance value.
    The key cylinder wiring is easily identified by 2 small gauge wires often enclosed in an Orange sheath. The resistance value measured at the base of the column, when the key is installed into the key cylinder, should match the key pellet value within a few ohms.
