I have changed all the fuses, computer, ignition module. I am getting fire to the distributor, but the spark plugs aren't firing.

Hi,
Okay, are you getting power to the positive side of the ignition coil when the key is in the run position? If you are, have a helper crank the engine to see if it still has power.
Next, remove the distributor cap and inspect the rotor and distributor cap to make sure nothing is damaged. Also, have a helper crank the engine with the cap off to confirm the rotor is turning.
Last, integral to the distributor is a camshaft position sensor that functions as a pick-up coil. That could be failing as well.
My primary suspect is a faulty crankshaft position sensor, see pic 3 below. By chance, have you replaced it?
If you have a live data scan tool, see if there is an RPM signal when cranking the engine.
Let me know what you find.
Take care,
Joe
