I need some more detail on that one before answering, what happens from when you put the key in to when you pull it out. A detailed description is best. When I tried to start my car by turning the key, nothing happened. It seemed like the battery was dead and then a few minutes later, a ticking wound came from below the gas pedal and I have no idea what is causing it.
A ticking or clicking sound is probably lifter noise, the valves need adjusting
the pullee to any belt could be bent
You have an old car or it's about to be broken.
that's just the sound of the steel bits cooling down
that probably means its time to get a new car
The most likely cause of a ticking sound in a motor is a bad timing belt. A valve out of time can also cause a ticking sound.
The tinking sound if it is a light sound is probably the fuel injectors working which is normal but I would check the oil level and make sure it is full first it could be lifters ticking or clattering.
Not enough power to starter motor.
the ticking is the blinkers
that would be the car indicator signal! that tells other drivers which direction your turning!
I don't know, take your car for a check up and tell them about it...
most likely a faulty relay
