Question about 1991 Lexus LS 400
My Lexus LS400 is not starting, only clicks when I turn the key. I replaced the alternator a year ago and I know its not the battery. I am trying the simpler things first as I have heard that the starter is a pain to get to...so, I am thinking maybe the starter solenoid or a cable? Does anyone have any ideas? I appreciate your help.
If the solenoid is clicking when you turn the key its very unlikely to be a relay fault, the relay controls the feed to the exciter wire which must be working for the solenoid to be clicking. If you haven't ruled out the battery completely do so by attaching jump leads, if that makes no difference you ideally need to check for a volt drop between engine and battery earth terminal and also main starter feed to battery positive, (the latter can be a problem with difficult to access starter motors tho.) if all wiring is ok its most likely the motor itself, if you can get to it give it a tap with something and see if it makes any difference. If it starts after a tap then its most likely the starter motor.

You may have corrosion inside your battery cables or a loose connection somewhere.
If you have a voltmeter connect one lead to the POSITIVE post of the battery and the other to the POSITIVE post on your starter while you have a friend crank the engine
WATCH YOUR HANDS!
This is called a voltage drop test and you should see less than 0.5v on the multimeter while you are trying to start it, if you have high resistance (corrosion bad connections) you will see a higher voltage. 0.5v is the MAX you should see.
Do the same test on the ground side of the circuit, connect to the NEGATIVE battery terminal and the starter case, your voltage reading should be 0.1v or less

slide the lower part of shifter handle down and you will find two screws, but there is 2 wires coming in from center console for overdrive button.you have to remove the center console cover and remove the 2 wires from connector and then pull up threw handle.when you go back together you will have to guide them back threw the handle.

Not too bad. Not much room, just enough to drop the starter. It is probably easier to go up through exhaust if you can get your exhaust shield off the manifold .

This is also possibility especially someone else drive your car. This is very common if you lend your car to someone. The symptom of this condition is "No noise or sound at all" when ignition key is turned. If this is faulty, the symptom will be the complete ignition kill. Therefore, you will not heard and clicking sound or engine turning at all. If this is the problem, you can easily reset the Anti-Deterrent by using your key. Stand out side of the car and close all doors. Insert the key into the driver side door and turn the key to clockwise and counterclockwise for three four cycles. Basically, you are lock, unlock for 4 times and this procedure will reset the anti-deterrent ECU. If this happen to you, its quite scary at first, but the solution is very simple.
