Check for battery power at the positive side of the coil, if you have power then I would just replace the points and condenser right off, then see if you have spark. If you don't have any power to the coil then start looking for a blown fuse or even a bad ignition switch.

Car has electronic ignition, so no points. Car does turn over, so assuming ignition switch is okay. Will check power to coil later today when I get home. Thank you for the response.

Ok electronic ignition, there you can also check for a trigger signal from the ignition module, just hook up a test light to the negative side of the coil and a positive power supply and see if the light flashes when the engine is cranked, if it flashes then the module and pickup are functioning properly, if no flash then I would replace the ignition module and pickup as a set so you know both are new. But still verify that you have coil power first. Now if you have both power to the coil and trigger signal on the negative side and still no spark it's a bad ignition coil.

Sorry for the delay. We installed a new key switch and ignition switch ( it didn't feel right when turning on, thought it might be bad). Car runs as long as we hold the ignition key in the start positiion. As soon as key is released, car shuts off.
