Dear cneuman
 
My first thought was maybe your battery is flat. A 2002 Lexus battery may be at the end of the road.
 
Good luck to you

Thanks jensad. I'm sorry, I forgot to mention in this discussion, replacing the battery was the first thing I did.
 
I appreciate your response.

A "flat spot", open segment, on the starter commutator will often have this effect. If you hear the "click" of the starter solenoid each time you turn the key to the start position the above is most likely the case.

Thanks wwest. No click. No sound at all that I could discern. However, I wonder now, if I'm missing that sound due to the sound of the steering wheel moving when I turn the key. If/when this happens again, I will pay closer attention. Anyone have any idea of what else it could be if there is indeed no sound at all?
 
Thanks to all.

the Alternator? Have you had it checked for output? Because obviously, your battery has been draining, if a jump will start it.
 
If not output, then you have some device on the car draining the battery overnight, like a radio that stays on constantly, or light somewhere. IF anything is hot in the car, that's your problem.....

Thanks nvbanker,
My mechanic has checked for what I'm told is called "parasitic drains", as you mentioned. The Lexus dealer and my independent mechanic both agree that if the problem is not happening when they check the car out it's very difficult to diagnose. This is very difficult, because, even if I had the car towed, it still might start, once it reaches the mechanic. However both also agree that if I hear a clicking sound outside of the car, which is very hard to do, by the way, when you're alone, that it could probably be the starter. In spite of knowing very little myself about the mechanics of a car, I too also thought that it could possiblly be the altenator or the starter. Since I was able to finally have someone else present when the car wouldn't start, so that they could attempt to start the car, I did hear a clicking sound while standing outside the car. I'm taking it to the mechanic today and hopefully this will be the end of this episode. I will keep you all informed, in case this experiece might help someone else in the future, as you have all helped me and many others with your knowledge and experiences. Sorry for the lenghty post.
 
And again, thanks to all.

Old Lexus 400 LS in Snow ? by 2driveright

Does anyone have experience with the first generation Lexus LS400 driving in snow? I'm considering buying one to be a 3rd car that will be a winter car. I understand the early 400's were derived from the Toyota Cressida and if so, I do have a lot of snow/ice experience with that car as I had a new one in 83 - 87 and found it to be very good in the winter here in NH. The Cressida was also a rear wheel drive car and with only a limited-slip differential, it handled deep snow and icy conditions very well. It was a rare car having an inline 6, a 5-speed manual trans, and 4 wheel disc brakes - really a great, reliable car.
So are the early Lexus 400's ok in the snow?
 
Thanks, driveRight in NH.

Stop by the general Lexus LS 400/LS 430 discussion and use the Search This Discussion feature for snow. You'll find a number of posts worth checking out. That's also a better place for your questions since this one is about starting issues.

Ooops...
Clicking sound not "click", as in a single click?
 
Clicking (continuous for as long as the key is held in the start position) is usually the result, A) low battery charge, B) poor connections from the positive battery post to the starter solenoid or the "ground" return from the starter to the negative battery post, or, C) an internal problem within the battery.
