Your distributor crank position sensor might be fucked. If you unplug this it will not start and will kill the engine right away. But if it's unplugged, there's *usually* an error code and you will definitely NOT get spark.

Have you pulled the plug wire boots and tested for spark during cranking at each cylinder?

After you test for spark ^^ and pull the spark plugs, are they wet with fuel?

If YES to both of those tests then look into your spark timing. Your distributor could have rotated and the engine fell out of time. Not likely but worth investigating if u have both spark and fuel... You can easily test for spark at the coil by unplugging the middle boot on the dist cap (from the coil) and holding it near a ground point during cranking. You should get lots of spark...
