Hello there.
Is this a permanent malfunction?
Have you had any work done on the car recently?
What happens when you turn the key? Can you hear any noise at all?
What do you mean by "auto start"? Does the vehicle have a remote starter?
Does it start now?
Did this only happen afte the battery went dead?
Will it start if you hold the key?
