It's, probably, your starter. Depending on what vehicle you have, a rebuild would, likely, be about $150.00 CDN, installed.
I actually had this problem with my first xbox. It turned out to be the hard drive.
you'll hear a constant clicking noise with no motor rotation, or you'll hear nothing at all
Type of noise - scraping, clicking? Type of vehicle? it's neither scraping or clicking it's kind of like a humming sound vehicle is 99 le Sabre
A clicking sound, when trying to start the engine, indicates a dead battery or poor (dirty) battery or starter relay connections.The clicking sound is the starter relay(soleniod) not getting enough power to hold it's contact points together.
Don't push that button.
Your bicycle, or your hearing is defective
Often, you will hear a popping or clicking sound when you are in a turn.
When the mount is broke off the engine you will hear a loud clicking sound from then engine being unstable and shifting around. Listen close enough and you can hear it shifting when the vehicle jerks.
Probable causes: loose cable or wire; faulty starter relay or solenoid.
Check your oil level-could be the valvetrain.
when we accelerate vehicle the supply of fuel gets increased .. Then inside the combustion chamber all the charge can't burn in such case so phenomena of knocking takes place.. So the sound can be heared.
Probably not, many cars have a switch on the clutch that allows you to start it while in gear.
