By "no spark at the coil wire going to the distributor", do you mean no voltage?
Do you have voltage from the wire coming from the ignition switch at the coil?
If the answer to both of these questions in "yes", you either have dirty posts on the coil, a bad wire between the coil and the distributor, or a bad coil.
You can check all of these with your multimeter set on OHMS with the ignition off.
