This code is most commonly associated with the crankshaft position sensor or the distributer.
Check that the sensor was not uplugged.
Remove the cap and gently move the rotor back and forth feeling for play in the shaft.
Timing is set by the ecm. The enhanced ignition system uses the Crankshaft Position (CKP) sensor in order to provide a timing input to the control module. Ignition Control (IC) spark timing for each cylinder based on this input. The control module provides the ignition timing signal to the Ignition Control Module (ICM) to control the ignition coil. Each timing pulse detected by the ICM allows it to energize the ignition coil. A large secondary ignition voltage is induced in the secondary coil by the primary coil. This high voltage is switched to the correct spark plug by the distributor.
