You'll need to test and see what is missing---the fuel, the spark or the injector pulse. That's the first step to getting anywhere without spending money guessing incorrectly.

On SOME cars (but not all), you can watch to see of the tachometer bounces while you are cranking the engine--if it does, then you know at least that your CPS sensor is working.
