Dont replace anymore til u know the cause--test for spark 1st-it may just be the ignition module--a worn coil--or bad distributer cap--battery cud be too weak and old-or alternator is------fuel pressure may be weak---------aftermarket electrics dont always work well either--a diagnostic scan can help at a privateshop

Try the ignition switch,
For the Crank sensor there is a small metal disc that mounts behind the sensor if that is cracked or dammaged or installed backwards you will get same results as if it wasn't Make sure the timing marks line up on your timing belt. www.kiatechinfo.com
SOURCE: car has no spark or injector pulse(new ecm,crank sensor)
Check the fuse for the injectors, some vehicles have the injectors and coil running on the same circut, at the same time check the fuse for the ignition.

Check the ECM if it has the number 1228253 on it, this is what is wrong with it. Gm trashed all of these bad ecms. Get a 16198264 as they do not cause a cutting off problem . Get a delco ecm , aftermarket units will give trouble and may be a rebuilt 1228253 which is junk.

Have you checked for injection pulse or compression. Will it start if you spray carb cleaner in the intake?

YOUR MAGNET IS ON THE CAMSHAFT.MAKE SURE YOUR CAMSHAFT SENSOR IS RECEIVING 12 VOLTS AT THE ELECTRICAL CONNECTOR.IF YES CAMSHAFT SENSOR IS BAD.IF NO POWER GOING TO CAMSHAFT SENSOR ELECTRICAL CONNECTION.YOU HAVE PCM OR WIRING PROBLEMS.
