Answer
If the car has a lot of miles on it then the timing belt may have jumped on the timing sprockets, you can also check to see if it's getting spark by removing one of the spark plug connectors put a screwdriver in the end and hold the metal part about 1/4" away from ground while cranking the engine the spark should jump to ground.
