If you ran it out of gas it's probably a plugged fuel filter, plugged fuel pressure regulator, plugged screen on the fuel pump or a burned out fuel pump.

Verify that you have good spark.


Mark is right. No spark and it wont run either. By priming the throttle body you are actually flooding the engine. I would also check the spark plugs to make sure they aren't fouled.
