Did you have a check engine light come on or has flashed prior to this problem and when was your last tune-up?

Cranks but no start condition:

Fuel and Spark:
Get a helper disconnect a sparkplug wire or 2 and ground it to the engine at least 3/16 away from ground -have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs, coil's resistances, distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it.

Ok then that makes more sense so if the distributor is shot and those sensors arent working then is tht telling the computer not to fire properly and to not let the coil spark?

You need to perform some testing here such as the coil and distributor pick-up coil
