You need air/spark/fuel to run. When it's not starting, check them independently of one another. I get intermittant spark due to high resistance in the female end of the speed sensor ONLY after it rains. I have to pop the hood, wiggle the sensor wire, and it starts right up. I diagnosed this by tearing apart the equation and saw that there was no spark (via a spark tester). It was intermittant though and took weeks of tests.
