When your solenoid receives a voltage signal from the ignition you can hear a "click" when it engages. If your engine turns over like it wants to start or you hear a clicking or a buzzing under the hood your starter works. If you turn your lights on after starting and they work it's not electrical at all. If you try to start it and you hear a high pitch whining type of noise and then your battery dies, then the teeth on your flywheel are gone.  The starter will just spin there and it will drain your battery with a quickness.

Why car wont start after killing the battery twice?


When you run a battery down a few times, over a year or so,
then kill it twice, in a row, in a couple days,it has to be replaced

Car wont start but lights work


Please provide with more detail. Does it make a click sound when turning the ignition? Does it crank?
Have you tried to jump the battery with jumping cable or tried it on a know good batteries?
- If the car does make a cranking noised then the starter is good but weak battery.
- If there is no noise or clicking, then dead battery.
- If you can hear the clicking when turning the key to start, then check for battery GROUND.
- If battery were tested and it read 12.5 - 14.0 DCV. Then your starter are bad.

There also other thing to check like security alarm system with ignition switch kill... But most common problems with fail to start are mention above.

2000 Pontiac sunfire won't start makes no noise when turn key over . headlights and radio work and dome light .. I have replaced steering column and ignition switch


This could be a couple different things causing your No-start condition. first thing I would check (Battery is good) access the starter solenoid, the small single wire connection is the start signal. Test for 12 volts here with DVOM or test light while someone turns the key. If there is 12 volts reading, the starter solenoid is defective. If there isn't 12 volts reading check all the fuses (with test light).
The second item causing the trouble could be the Neutral Safety Switch (Auto Trans) or Clutch Safety Switch (Manuel Trans) These could be open or out of adjustment.
Hope this helps you...

2003 ford explorer wont start hear a click under the hood, i tried to jump it and it wont start. do u think it needs a starter?


Go under the car and have a helper hold the key in the start position while you probe the wire to the solenoid for 12 volts, also do a voltage test on the positive battery cable and inspect it at the battery for acid intrusion near the positive battery post clamp, if acid has gotten into the cable the outer insulation will appear swollen and the cable must be replaced, this is a common cause of no starts on Explorers.

2001 ford windstar clicks when you try to start it, and will not run.


This procedure usually works:
  • Check the battery cable connections:
Make sure the positive cable, makes a good connection at the battery and at the starter. Make sure the negative cable makes a good ground connection at the battery and (preferably) at the engine.
  • Check the battery the simple way, like this:
Turn on the headlights, then try to start the car.If the headlights do not dim or go out, then the battery is likely ok.
  • Check the starter and solenoid:
If the wiring looks ok, then look at the starter solenoid for a good connection, and proper voltage at the starter(10 volts minimum while cranking).
If the starter spins and no crank, the problem is most likely the Solenoid's bendix gear is stuck.
Have someone hit (not too hard) the starter while you try to start the car. This usually works by dislodging a stuck bendix gear.
  • Make a simple test of the alternator:
If you can, somehow get the engine running, measure the voltage at the battery. It should be at least 13.6 volts to properly charge the battery.

Won't crank. Turn key and nothing happens. I turned the lights on and they worked so I don't think it is the battery. anything??


sounds like a faulty starter, if you can get some help have someone hold the key over to start
you should get voltage at the solenoid trigger wire (thin wire) if you do give starter a tap and it should spin.
if you have an alarm system the starter kill may be activated.

When trying to start the car I get nothing upon turning the key over. The starter isnt clicking, I was told it was the cellinoid(sp?) and tried replacing that and getting the same results. I checked the...


I would check all the heavy cable connections on the battery, both wires on the solenois and at the starter connections (a little dificult to reach) Give each connection a good twist and make sure it's tight.

You can energize the solenoid manually if you are electonically enclined.. Or better yet, if you have a Volt/Ohm meter, measure the 12V. signal to the solenoid when you turn the key to start it, (measure across the solenoid terminal smaller wires). Be careful doing this.

Any questions,....reply here..good luck.

Car wont start, makes a clicking sound under the hood


When you turn the ignition key to the start position you apply 12 volts to the solenoid. The solenoid is a relay switch that closes when you turn the key to the start position. When it closes It applies 12 volts to the starter motor.The starter motor draws a lot of electrical current, (so much so that they could not run that current thru the ignition switch, so they use the solenoid) What you hear clicking is the solenoid closing, or trying to close.I assume that "*****clicking" as you define it is a chatter rather then one click.

Possible causes: A low battery voltage. Has the battery been replaced in the last few
years few years. Try charging over night and see what happens
Bad connections on the battery terminals. Check for any white powder on and around the battery terminal. Use baking soda and water to clean the terminals (it'll fizz) then clean theem with a terminal brush. You can get one at any auto store
Bad connection on the starter solenoid
If it a manual shift, there is usually a kill switch somewhere on the shift mechanism
that prevents the starter from working if the car is in gear and the clutch is out
In automatic shifter the kill switch is in the shift selector mechanism so you can't start the car unless you are in park.

Hope this helps Lood luck Loringh
