First thing I would check is the ignition coil.

You say you are not getting spark - Does that mean you removed the plugs, and saw that they did not spark as the engine was turning over? (If not, check that)

If no spark, I'd start looking at what is supposed to work to GET a spark...in addition to the coil:

How old are the plugs, and, wires?

Hows the distributor? Can you see it turning in there as the engine is cranked?

Is there a loose ground strap anywhere?
