No Spark.

Yes, Clean out the distributor! Clean it real good & blow it dry carefully with compressed air. Both inside the distributor & cap & outside the cap in each secondary terminal(plug wires)
Check for Voltage at the coil +, get a test light(illuminated ice pick) or a volt meter(better), have someone crank the engine over normally & check the negative side for a trigger or blinking test light- voltage change down/up on the voltmeter. That'll tell you if the pickup & ECU(ign. module) are working. If good there bad coil- assuming you have checked for spark at the coil as suggested earlier. If no good on the tests above go over ALL the connections in the primary side of the ignition & check voltage in & out of the Ballast Resistor.
