Fuel pump
if you turn the key and nothing is making noise check the battery if you are trying to start it and it is making noise press the gas a little bit so that the car can pump gas into the engine
Check your battery.
most likely a loose or worn belt.
check the charging system.... pay close attention to the belt that turns the alternator
Is it making any kind of noise or is it not doing anything at all when you turn the key?
If your car doesn't start, or when you turn the key it makes a weird noise. Lights dim, slow to turn over,
Starter relay is broken
Make sure it is in park. Clutch pushed in. Dead battery.
When you turn the key on, if the buzz is coming from the back of your car its your fuel pump, replace it and the car will start every time.
If you mean the car will not start or even turn over when you turn the key, that 'clicking' is the starter solenoid making contact like it's supposed to. But there is not enough power from battery to start engine, only enough to make contacts in solenoid. Bad battery, or loose or corroded battery cable terminals
If the Car didn't start with the key turning the ignition then the car was "hotwired" to turn the Car on.If the key did not start the car, how was it started.
the only way to start a car when the remote key is dead is to start it by putting the key into the ignition.
