First, Is the battery Okay? If the battery is dead or near dead, you will be able to crank the engine and then not hear anything but clicks as the starter solenoid engages or tries to engage.Can you get jump from someone with cables for the battery?If not that, try looking at your engine on top and make sure none of the spark plug wires have become disconnected or broken. if it's not gatting gas, perhaps you have blown fuel pump.
