SOURCE: 92 Lexus LS400 only clicking noise when I turn key to start

There are a number of things that could cause that. Try turning the key to the on position and crossing the starter terminals with a screwdriver. If it starts you have a bad ignition. If it still just clicks your starter has seized up or your battery might be lacking the charge to do the job. Hope these help you.

SOURCE: my car won't start up and i got a good baterie

The clicking sound is made by the relays. Most probable is the induction coil is damaged, thus not producing the spark for ignition. You can check it out by removing any one of the cables from the plug and hold it near any metal part of the engine block & have someone crank the engine. If no sparks fly out then the coil needs to be replaced.

However do check the fuses behind the dashboard on the drivers side first!

I called myself programming the new keys for my pt cruiser, but,it didnt take. At first it would start and run for a few seconds, now it wont turn over.what did I do wrong and how can I fix this?

Takes the master key to get it started again. The security gives you 3 tries to get the vehicle started, after the third time, it kills the starter.
2002 Chrysler PT Cruiser Note: You must have two valid keys to add a new key to the system.
1. Insert the first valid key into the ignition switch. Turn the ignition switch to the
ON/RUN position for at least three seconds, but no longer than 15 seconds.
Then, Turn the ignition switch to the LOCK position and remove the first key.
2. Insert the second valid key into the ignition switch. Turn the ignition switch to
the ON/RUN position within 15 seconds. After 10 seconds, a chime will sound.
In addition, the Vehicle Security Light will begin to flash. Turn the ignition switch
to the LOCK position and remove the second key.
3. Insert the new key into the ignition switch. Turn the ignition switch to the
ON/RUN position.within 60 seconds. After 10 seconds, a single chime will
sound. In addition, the Vehicle Security Light will stop flashing. To indicate that
programming is complete, the Vehicle Security Light will turn on again for
seconds and then turn off.
The new key is now programmed. The Remote Keyless Entry transmitter will
also be programmed during this procedure.
Repeat this procedure to program up to eight keys.

Security light flash no security system on truck

sometimes turning the ignition on 3 times quickly without starting will reset the computer. If the van has power locks and keyless entry then try using only the keyless entry. Sometimes your car wont have a alarm but an anti theft device which will not allow it to start if it goes off or something triggers it.

Hi,First you should take any wires of that were installed before that causes major problems.If the key has a chip on it you may have to get another one made ,if it got very wet.If the security light is flashing,you can try this.1.turn the key to the run position but do not start it.2.leave the key in the run position for 10 to 15 minutes or until the security light stops flashing (becomes solid)3.if and when it becomes solid turn the key to the off position.4.wait 10 seconds an try to crank....If it wont crank or the security light keeps blinking.You will have to take proof of ownership (title) to the dealer and they will make you another key
