Q: Just replaced battery and brakes, why won't my starter engage?

Why won't my starter engage when all my instrument are working

My car has 202440 miles.
My car has an automatic transmission.

Hi There, It sounds like you may have a faulty starter solenoid or starter relay. If you hear a clicking sound when turning the key, it is likely that your starter solenoid may be faulty. The starter solenoid is located on the starter and has internal electrical contacts that transmit electricity to the starter. As electricity is supplied to the starter a small gear comes out and engages the flywheel to spin the engine over as you turn the key. When this fails, it may cause a clicking sound and will not allow the starter to engage the flywheel when you turn the key.

The starter relay directs power from the battery to the starter solenoid which then engages the starter when you turn the key. When this is not working properly, you may notice intermittent starting problems including no response when turning the key to start. Generally, when this does fail, it does so very randomly and usually without warning other than intermittent starting. The power from the battery will still power other accessories such as radio, horn, etc., but you may not have any power to the starter. I would recommend having an expert from YourMechanic come to your location to diagnose and inspect your vehicle.
