Q: I have a Nissan Sentra and my car just suddenly won't crank. I had the starter removed and checked, which turned out to be fine.

Hello, thanks for writing in. If your vehicle will not start and you are hearing clicking noises then the first thing I would do is check the starter relay, which is different from the starter. It is not uncommon for relays to produce a clicking sound when they go bad. If the relay responsible for switching power to the starter goes out then it will leave the starter without functionality. I would test the relay, replace it if necessary, and go from there. If the starter turns out to be fine or if you are still experiencing problems, consider having an expert automotive technician from YourMechanic come to your home or office to inspect and diagnose this issue for you, and make or suggest any repairs as needed.
