Car makes one click when I turn the keys but car won't start

You might have a new battery, but that doesn't mean your battery is providing full voltage to the starter. After driving is for a while, the battery is charged and able to provide 12V to the starter solenoid. After parking it for a while (10-12 hours) the battery might have been drained by a parasitic drain and unable to provide 12V to the starter. You might want to perform this test and see if you have something draining the battery when the car is off --- http://www.wikihow.com/Find-a-Parasitic-Battery-Drain

Car: 2007 Honda Accord, 108k miles, 2nd Owner, Fall/Winter - Battery replaced a few months ago - No sign of corrosion on the battery - Takes a few tries to get the engine to turn as well - Once the engine starts it runs absolutely normal I've been running into the exact same issues as you are. I initially thought it was a dead battery so I tried to jump starting it with no luck. So today I was having the same issues as well and after some research, I used a hammer to tap on the starter a few times thinking it might be a loose starter solenoid. I realized that I've been having this issue during the Fall/Winter season and checked my antifreeze/coolant and found out that it was very low and might be the cause of the engine freezing up. Then I drove it around for a few blocks hoping that the coolant would be distributed. The car seems more responsive, normally before I put the coolant in it would take about 4-8 attempts to turn the engine and now it only takes a few times to turn over. I just tried this today so I'm not exactly sure if this is the exact solution or not but I hope it helps you and anyone else with this issue! Good Luck! - K.S.S.

MINE IS A 2010 CAMARO, WHEN CAR COLD IT STARTS EVERYTIME BUT AFTER DRIVING IT AND TURN IT OFF I GO TO START CAR AND YOU CAN HEAR SOLINOID CLICK ONCE AND AS I KEEP TRYING TO TURN KEY IT WILL EVENTUALLY START. REPLACED STARTER ABOUT MONTH AGO BUT STARTED DOING SAME THING OVER AGAIN. WONDERING IF IT MAY HAVE TO DO WITH CLUTCH.

I've been having the exact same problem. Whenever the car is driven, I have no problem starting it back up. But when it sits overnight, all I get is that "one click". I have a new battery now. I thought it could be the starter, but I'm not sure. Because why is the starter only not working when the car goes a long time without running?

I have a Mitsubishi Eclipse 2003 clicking when turning over the key behind the exhaust manifold on the front of the motor New battery Alternate any ideas ?

Well, my problem was with the starter. I would get one click every time I tried to crank it up. I removed the starter from the car. The two copper contacts inside of my starter solenoid were worn down. So I ordered a pair along with a plunger off of Ebay for about $13. Once I replaced those old contacts, the car crank right up. There are instructional videos on the web that will show you how to do it. Not sure if this is your problem GuruSD5Z6, just telling you it resolved my issue. Some mechanics will tell you to get a whole new starter. It's not necessary in many instances. Just replace those copper contacts inside of the solenoid.
