Why isn't my 1990 lexus ls400 not getting a spark after sitting overnight?

My car runs perfect and then it sits overnight. In the morning I try to start the car it just turns over not getting a spark.What would cause this problem?

Thats a hard one,it could be a bunch of things sensers,opening,closeing,getting stuck,I am not a mechanic,but I have had about every model made,I have wholesaled many units,and if something would go wrong it happen to me,there is a lot of electronics on that car,there very nice to.It just sounds like a senser not opening or not closeing,Just stuck.I would start in getting a meter put on it while it's running and a complete check out,then you'll be able to have a starting point.They'll be able to tell if it's some kind of electronic problem like a sensor,and there are plenty of those on it.Fuseable link,not working porperly,map sensor,I would start from there.When something shuts down like that,like a sensor ora link,you'll be able to tell.and it is not that exspensive to have done.Call the dealership and ask them how to get the code out of it,sometimes it's like turning the key back an forth like 3 times,a caddillac gives it threw the radio,a chrysler gives it threw the parking light.Etc.sorry I was not to much help.

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.

Had the same problem. In my case, it was the battery cable ends that needed replacing. Car works fine now.

Electrical problems,won't start in morning after sitting overnight,with boost it starts immediately

Have your battery load tested at auto parts store. Do it while still in the car. They can also check your alternator at the same time. It sounds like you either have a short that is draining the battery as it sits overnight or as your vehicle runs the battery has enough charge to run but not enough charge to last it UNTILL the next morning.

91 lexus ls400 will not start

Could be several things.
If the head gasket is blown, you may have lost compression in the cylinders. You may have also damaged the spark plugs with coolant.

My Lexus LS400 was running perfect - no issues whatsoever. Today it won't start. Have tried jumping it but no luck. It acts like it is about to start but won't.

sounds like an engine immobilizer problem. close all doors,hood & trunk completely. lock and unlock the car three times with remote, then put key in door lock and lock & unlock three times.
did you accidently try to start with wrong key?

My 91 ls400 acts like it vaper locks dies out has to sit awial then actes like it has low power for awial then serges to normal what may be the problem?

this is a computer problem. 91-96 lexus ls400 are known for having their computers go out on them. I would have never believed it but my ls400 did the same thing. I sent the computer to Auto Computer Exchange in Davie FL. They reprogramed it for $310 sent it back to me in a day. It fixed the car. I have had no problems out of the car. I now work on ls400 on the side to fix the same problem for other people.
