2005 nissan altima won't start, clicking noise is heard

check your radio fuses-one under hood and another under dashboard.usually after power cut you have to re-enter radio security code to get it going again most car scanners can retrieve it if you don't have on.

older model altima need drive belt tension adjustment at 7500 miles intervals, the new models altimas has a automatic belt tensioner.i you hear noises belt tensioner could be failing.or could have leaking coolant getting on drive belt due to water pump gasket leaking or pump leaking.or alternator power steering pump could be failing many things will cause drive belt to make high squeak noises.

The click is most likely the starter solenoid you hear

Should be a familiar sound you've heard may times
on other cars

I would guess you know how old the battery is?

If it is original,it is 8 years old & dead,if so, replace it

If it is only 3 years old ,check the voltage with a meter

Next the solenoid could be working as you hear it,but
it's contacts are burnt,it can be replaced

You remove the starter & change the solenoid

Don't want to do that, buy the entire starter at auto parts,
not a dealer,cost too much to even be there for any reason.

check fuseable link near battery if it's blown would pay to look for short circuit before doing much more

you may have a problem with the clock spring or spiral cable as nissan calles it. it is a part of the air bag system and also horn signal runs into and out of it.if that part is bad, your air bag light will flash and your horn will not work. has anyone been doing any repairs inside of the steering wheel?? it may just be unpluged. if you are going to tackle this your self to look inside of the steering wheel, make sure you disconnect the battery for at least 3 minutes, befor you start playing with the air bag. you dont want to blow it up.

I, feel sorry for you, after reading your problem, but don't worry you visit the Reliable-Store they will help you for sure.They have repair manuals at a very less cost.

When a car wont start clicking noise is the only one you heard then the problem involves your battery, have your battery check first.

i would check the antenna connections

sounds like you need to check the connections from the battery to the starting motor and you may also need to check the connections to the solinoid motor as well

i had the same issue had the alternator replaced and their is no longer a noise.
