Both my sons, in their 20's, drive early LS400's. They think the car is really cool. Ok, I *might* have tainted their judgement a tad bit and given them Lex Fever with my LS's.

Good job. I am so jealous of your parts cleaner system!

Now, I would not classify that as "sludge" on your valve covers but as "vanish", which is very common to most higher mileage engines.

Take the meter and check for voltage between the +B pin and ground. It should be +12vdc when you first turn the key to "on".

It could be your starter relay but not likely. Still it would not be a bad idea to check the relay. Failing to crank is not the ECU if you are hearing the click of the starter solenoid contacts...

Yeah, I am glad you asked too. I do not want to see sparks flying any more than you do. Just ask if not sure. So, you found the port connector ok? Its just a few inches beyond where the top radiator...

If you open the hood and look at some of the engine parts, it has "Toyota" stamped all over the place. For good reason. Its Toyota (high end) with a Lexus badge.
