Battery in good shape but when I turn key I hear only one click. What could be the problem?

If the click you hear is from the starter solenoid mounted on the starter, it could either be a bad starter or poor connections between battery and starter. Raise the hood and listen closely near the starter for the click, when someone turns the key to crank. If the click is from the starter solenoid, have starter tested or replaced. If click is from a relay under the hood, then the start circuit will have to be further diagnosed.

Hi Charotte,your engine is not a interference engine.So your in good shape.

Hello! Do you hear a click when the key is turned?...If no click is heard either the ignition key, the Crank relay, the starter, or the battery are suspect...Having lights and radio does not mean the battery is capable of running a starter motor......Put a meter on the battery...should read 12.5 volts...Turn key...Does voltage drop to 8 or 9 volts? Bad battery...If all is well with battery and connections to it...Check the starter fuse # 33 in the under hood fuse/relay box...If the fuse is good that click you should hear is from the Crank Relay in that box...If all of the above is OK connect your meter to the Purple wire that is connected to the starter motor...When the key is turned 12 volts must be on that wire...If there is the starter motor is defective...So, #1...Do you hear a click when key is turned...That would point at a bad starter or weak battery...#2...If you do not hear a click bad fuse #33, bad Crank Relay, bad ignition switch...#3...If fuse is good Bad Crank Relay or Ignition switch; Crank Relay is a low cost item ($10)...Replace Relay...Stop there and send a comment as to results...Guru...saailer

Did you have the battery checked by a doing a load test? Do you hear a "clicking" sound when you turn the key to start? If you hear a clicking sound, and you're positive the battery is good (fully charged) it could indicate a bad starter solenoid.

By the way....what kind of vehicle is it....a 00 Camry or an 04 Impala?

Ive got the exact same problem..should I replace starter?

Check your battery connection's, if when it clicks one time do the lights go off?Then more then likely bad battery connection.With light switch on move battery connection if lights come on you found your problem.

Starter ignition switch may have gone bad under the steering coluum

If you don't hear a click when you turn key to Start, check that the small wire onto the starter solenoid has a good connection. If you do hear the click, check that the large wire going between solenoid and battery has good connections..hope this helps.

Check the tremianls on the battery. also follow your ground cable to where it is attached to the frame, motor or body. if the cables are in good shape, cut off the old terminals and replace them with new ones from the parts store. They are only a couple of dollars each.

Listen for a click from under the steering column when you turn the key on. If you hear no electrical click then your ignition switch could be bad. If you hear an electrical click the you starter soleniod is bad.
