i have a 1997 lexus es300 that i left in my garage for a couple of days because i went on vacation. after i came back, i started the car and it made a few cracking noises and stopped. Whats wrong with the car?
EDIT: Okay here's my serious answer. It could be that your battery is low or dead. It's too cold, hot. Or your engine just want turn over when you turn the key.
