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.

Low fuel pressure or problem with spark plugs or crank sensor is got dirty and needs cleaning or its time to replace crank sensor.


Check out the help links shown below for no start problem and cranks but no start problem.

It can be the issue with weak battery or faulty battery or if battery is ok,then its faulty starter causing the issue.

1990 Lexus LS400 Service Repair Manual Download Try it asap.. I bought today. it's very cheap and very reliable. today they have offers as well.

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.
