You didn't state in your post if the engine is cranking so I'll assume it is,First make sure threr is gasoline in the tank (last week had a car towed in 53 miles because it was out of gas) remove the air cleaner and press down gently on the air flow meter feel for resistance and listen for high pitched squeal. If thats OK you may have an ignition problem if not then probably need fuel pump relay.
Good luck Mike
