The parts you listed have nothing to do with cranking the engine. Depending on what kind of buzzing you're hearing, it suggests the battery is defective, run down, or has bad cable connections. Start by measuring the battery voltage with an inexpensive digital voltmeter. It should be near 12.6 volts if it's fully charged. If you find closer to 12.0 volts, recharge it. If it's less than 11.0 volts, it has a shorted cell and must be replaced.
