Hi,

Have you confirmed there is power to the coil? I would start there and work backwards. However, (and don't laugh), remove the distributor cap and confirm that the rotor turns when the engine is being cranked.

I attached the powertrain control wiring schematics below. Take a look through them and see if anything helps. Note that I cut the pic in half to make it readable for you. I did overlap the two to make it easier to follow.

Let me know.
