It can be a dead battery, or a bad starter, the click sound you hear is from the starter relay mounted on the inner fender near the battery, use a test lite and make sure power is coming out of the relay and going to the starter, always replace both the starter and relay if either is found to be bad
It could be a bad starter or a bad solenoid.... If you turn the key, but motor will not turn, listen for clicking... if it clicks, possibly bad starter. best option would be to beg steal or borrow a voltmeter and measure voltage at starter motor when key is turned......
Could be,low battery, loose or dirty battery connections, starter is bad, starter solenoid is bad, neutral safety switch bad or out of adjustment, starter relay is bad,
It could be the battery. If not try tapping the starter with a hammer. Not hard enough to crack the housing but hard enough that it might unstick the starter from the flywheel. If this works you might want to change the starter. If not it would have to be the solenoid.
That means the solenoid IS working, but power is too low to turn the starter. Check and if necessary clean or tighten the battery terminals. If still the same, charge your battery on slow for at least 12 hours, or get another battery.
if the battery has enough power, it could be the starter itself, poss a bad spot on the motor, could be a bad connection at the starter or positive battery cable, maybe corrosion on the terminals.
This sounds like your battery.

Could be bad glow plugs.
Could be the Starter or the Transmission
If the battery is bad, you may only hear clicks. It could be the starter, but I would check the charge on the battery first.
your battery is flat Could be that your starter is dead. The clicking is the starter solenoid. That's a good thing that it is at least clicking. Replace the starter.
starter, solonoid, ignition, battery. if it clicks when you turn the key then the battery is really dead or its the starter the battery could still be jumped if its the battery.
Could be,low battery, loose or dirty battery connections, starter is bad, starter solenoid is bad, neutral safety switch bad or out of adjustment, starter relay is bad,
Try and turn the Impreza engine over by hand. The engine could be locked up and not let the starter turn it over.
Check your battery first, its terminal connection and connection leading to the starter.
It could be starter, battery, keyswitch, neutral lockout switch or electrical connections.
Proper battery connections could be at fault, how old is your battery? Check for loose and corroded terminals on your battery and starter connections. Also the starter might just be bad.
