Maybe flat battery?
clicking noise when trying to sart engine usually indicates a flat battery.if the battery is not the problem ,the starter motor needs repair.
If clicking while trying to start then might be a bad starter. If clicking while running, then might be valve/lifter noise.
it might be your starter.
Sounds like your battery needs replacing.
Does the engine turn over and then make the clicking noise while trying to start, or does it not do anything but make the clicking noise when you turn the key. If its not turning over at all then it might be a battery problem, Try cleaning the battery terminals, and/or charge the battery, Could also be the starter solenoid, but start with the battery first.
Why is your 1993 Altima Nissan making a clicking noise but does not start?
Needs a new starter
If the 1996 Olds Aurora will not start and there is a clicking noise from under the front panel, check the starter. The clicking noise is probably from the starter solenoid.
I don't know what "after battery is off" means, but if it is clicking while trying to start, then most likely the starter/solenoid/relay is bad.
A loud fast clicking noise is usually indicative of a low battery or a loose cable.
