What causes no spark, it is not firing, no spark from the plug wire to the spark plug?

Hi,

Make sure the distributor is turning when the engine is cranking. Also, check the pink wire at the ignition coil to make sure it has power with the key in the run position.

Next, if there is no power, check the ECM1 fuse in the underhood fuse box.

If there is power at the coil, then confirm there is a ground path to the PCM via the black wire at the ignition control module (ICM). Also, let me know if the ICM has been checked or replaced.

Let me know what you find.
