Based on the information provided, it sounds like you may have a problem with the starter motor or the starter solenoid. When you turn the key in the ignition, the starter solenoid should engage and send power to the starter motor, which in turn cranks the engine. However, if the starter motor or the starter solenoid is faulty, it may not be able to crank the engine, and you may hear a clicking sound instead.
One possible cause of this issue is a weak or dead battery. A weak battery may not have enough power to crank the engine, which can cause the starter to click instead of engaging. You may want to try jump-starting the vehicle or testing the battery with a voltmeter to see if it has a proper charge.
Another possible cause of this issue is a faulty starter motor or solenoid. If the starter motor or solenoid is worn out or damaged, it may not be able to engage and crank the engine. You may need to have the starter motor or solenoid replaced to fix this issue.
It's also possible that there is a problem with the ignition switch, starter relay, or other electrical components in the starting system. However, given the symptoms you've described, a faulty starter motor or solenoid seems like the most likely cause of the issue.
