Timing chain or cam.
Check the rotor and see if it is turning when you crank it.
It could also be the distributor gear.

Unplug the EEC Computer and see if you have spark then, if you do the computer is bad.

It is in the drivers kick panel but you need to unplug it from under the hood with a 10 MM 1/4" drive socket.

Should work.
Sounds like you have a wiring problem, maybe the SPOUT wire is shorted to ground, unplug the SPOUT at the distributor.
Do have power at the coil with a test light?
Power to the Ignition Module?
If you have power to the coil does the tach side of the coil flash when you crank it?
Also the Ignition Coil plug may be bad.

Put the spring clip on a good ground and the point back probing the connector. Note if the plug is bad even if the test light shows power the coil may not be getting it.
