It is probably the coil or the ignition module, but if you remove the distributor cap and crank the engine over is the ignition rotor turning? If so, I would start by checking the fuses. This guide can help:

Please test with the key on. Next let's see if the positive side of the coil has power with the key on, this guide can help, (pink wire).

Here is the location of the ignition coil. Check out the images (below). Please let us know what happens.
