I have been trying to reply each and every day for almost a week, this Forum kept on returning an error code and sending error messages to window every time I tried to make a reply. I even replaced my computer registry with an earlier version, sorry about the wait. It turned out to be a bad connection on the wiring harness behind the intake manifold. In reply to WestCoastSooner, I would take the car in for that price. I have done a lot of work on vehicles of all makes and models including converting auto transmission to manual and complete engine rebuilds. I have found Lexus a pain in the rump to work on. The fuel injectors are very sensitive, tiny little O rings the Toyota dealer nearest to me wanted $4.65 a piece times eight. Napa had complete injector kits to $1.99 each that incluced the four seals per injector necessary to reinstall the fuel rail. Thank God this job is done and I want to thank everyone that put up a post that !Removed! isted me in completing this job. I also replaced the timing belt and changed spark plugs, the car has 103K miles.

I have voltage to the starter main terminal, I also have a good ground, I do not have any voltage that is going to the trigger wire at the solenoid when the key is turned in the ignition switch. I do have a click in the relay, could this be either the park nuetral switch or the ignition switch.

I replaced the starter because it would click and not start the car. We would have to rock the car and retry starting the car, it behaved very similar to a bad solenoid. I did check voltage between the positive connection on the starter and the ground on the battery and voltage was present. I have checked all of the fuses, the starter relay clicks which makes me think the starter switch is working. I talked to Lexus and he stated that he did not think there was any computer fail safe that would prevent the starter from cranking. Plan on taking off the intake tonight and try the suggestion above connecting the starter directly. Any help from any techs or someone with experience would greatly appreciated.

I have spent the last couple of days replacing the starter on my 2000 LS 400. This is a very difficult job, you have to pull the intake manifold to get to the starter. Everything on the replacement went fine except, when I turn the key the car won't start. Replaced another starter, same result. Is there a computer problem that is preventing the car from starting. Any help or suggestions would be greatly appreciated. The engine will not turn even while torn apart, I can hear the starter relay working, no click on the starter, nothing!
