Car won't start but keep hearing a clicking sound.

With a voltage meter see how many volts are at the starter terminal. If not 12+ volts you have a bad connection. Check connection at the starter solenoid. Does it have 12+volts? Short the solenoid. Does it put voltage to the starter?

With headlights on, try to start the car.
While engaging the starter: Do the lights dim? Do you hear anything? If so, what do you hear?

try this.. disconnect the vehicle battery entirely, connect a 10 amp battery charger to the car connectors matching the terminal leads..and power the car with the charger..you should hear a hum or buzz in whichever relay or circuit breaker is bad.. replace this relay and the lights and stuff should work..the charger will not direct-short but the guage may go full over indicating a malfunction..or extreme load.. maybe a window switch might be fried..you should be able to hear any issues as long as power is coming from the charger only...repost findings..

Yes.it takes more amps.to start your vehicle than run the radio

When you do turn the ignition switch if you do not hear anything is possible the starter motor solenoid.,check also the battery terminals for miss contact,remove and brush the dirt between , or bad earth.

the clicking that you hear is coming from the starter relay. sounds like your ignition starter switch or ignition lock cylinder is bad.

i have a 91 camry Dx the radio and lights come on but the car won't start up i don't hear any clicking sound when i try to start the car up

check your starter,better yet has your alarm system been activated and possibly shut down your car a passive alarm will do that

If lights work, radio but not turn over. First of listen to see if it clicks when turning key, if that happens most likely it is the solenoid on the starter not triggering, if you hear nothing when turning the key, then the cable coming from the battery that goes down to the starter is loose, bad connection. Make sure that the cable from battery is tight, and clean. If Like I said you hear a click when trying to start car, then it is starter/solenoid issue. I hope this helps, if it does please rate my free advice accordingly> Thanks Mike. and check out my personal expert site....

it sounds like the starter has failed. it needs to be tested by a trusted technician near you.
