#1651 of 2081 92 ls400 will not start
Aug 15, 2005 (10:16 am)
My car was driving great I noticed anti freeze under the car one day so I put some stop leak which it worked for 1 week. I was at a light the car was hot making that winding /clicking noise when it get hot but not smoking and the temp gauge was normal. The car stalled on me and wouldn't start back up. I let the car roll back to the curb and parked assuming if I leave and come back it should cool down and start back up, which it didn't just cranking but won't start. I towed it to midas they only mentioned that the timing belt was popped and saying my car was an interfrence engine and that 99% chance that the valves were bent. after telling that and the price to just fix the timing belt $550 never mentioning anything about the leaking anti-freeze I had it towed to my house. The next day I had it towed to another shop and they said the waterpump had seized up popping the belt so I paid him to replace the belt/ waterpump and it wouldn't start, he then said this was an interfrence engine that my valves could be bent but i did a lil research and found out my car isn't a interfrence engine they didn't start that until 1995 ls 400 My lexus dealer confirmed it so my valves should be fine. He said he did a compression test and the left side had none . I had got another opinion saying he may of not set the timing right to read no compression. I had this guy resett the timing which the other guy was off he showed me the marks. He reset them and had me try to start the car it sounded better trying to start then before but it wouldn't start. he tested for fuel delivery that was fine, he tested for spark which it had none at all. he suggest me changing one of the ignition coils which I did today but it still won't start. Any ideas,suggestions that may help get my car started?

Timing that engine ( cams -crank ) is a big job are you sure they have it right? The replacement belt has the timing marks on it . Are they using the Lexus shop manual ? Has your mechanic checked for any engine codes ? As for the coils check for 12 volts at the coil + terminal with the ign on to see if power is supplied , those same coils are on many Toyotas a 94 4 runner v6 uses the same one as your Lexus . Check for spark using the coil high tension lead disconnected from the dist cap and held about 1/2 inch from body grd. Good luck

hello, the timing marks up top was lined up and he had the bottom on "0". my car is at my home now which there isn't any way to check codes no tester. my check engine light has been on for long as i had the car 8 mths but the car drove super! just before the waterpump went bad and the overheating came into the picture. I noticed the car had stalled on me a couple of times while low idled foot on the break but started right back up which it never did that in the earlier 8mths. Question if there is a bad sensor would it prevent the car from restarting if it failed competely paul29
#1654 of 2081 Buying a '96 LS400
Aug 18, 2005 (11:26 am)
I had a '90 LS400 that I sold last year with 200K+. Awesome car.
The bug has bit me again and I want another LS. I've been looking at '95 & up models for the past month and haven't seen anything I felt I wanted to make an offer on until yesterday.
The car is a silver 1996 LS with only 75K. Seller is asking $13K.
The Good: the car had 1 local elderly owner and who put on 75K. Drives very well. Very smooth. Clean and sharp looking with chrome wheels.
The Bad: no moonroof and no CD (odd for an LS), one minor 5" scrape on the front, a couple scratches on the rear bumper, and a couple missing pixels in the radio LCD. Big-O tires. Hmmm.
The car seems to have been serviced at an independent, but not one that really knows the LS. This is my biggest worry about the car. There's NO repair work that's been done.
So I'm thinking - at 9 years old this car could need some work in the near future.
Timing Belt Change (past due in terms of time, if not mileage)
Lower Ball Joints, Knuckle Bushings
The likelihood that all these things will crop up soon is low, but I want to think about what the car might need in the near future so I can plan ($$$) accordingly.
I'll get the car inspected at the dealer or a Lexus specialist, but I'm kinda worried about seeing no repairs done on the car.
Also, the price seems high - I think $11K is about the most these cars fetch.
What do you guys out there think?

#1656 of 2081 replying about water pump failures and timing belts
Aug 18, 2005 (7:39 pm)
I read different messages about people having water pump problems I have found that I use the Toyota antifreeze mixed with distilled water mixed 50/50 every two years I dump the water out of the radiator and out of the engine block. I always empty both and just refill both and you have to be careful not to get an air bubble in the system. There is a bleeder valve on the front of the motor for this purpose. Also I see a lot of you folks complaining about the power steering pump leaking. Yup they do and the reason is the fluid gets hot and most people never change the power steering fluid. I change it every 30-40 K and I use Mobil one
synthetic transmission fluid to keep the seals soft and keep down the heat. I also saw someone was told that the older Lexus engines would break a valve if the timing belt broke no not normally I recommend changing the timing belt at 90,000 miles with the water pump and the idlers pulleys and all fan belts this way you take care of everything at once. Another tip use the two dollar car wash to clean out your condenser and radiator
to help run your car cooler during the summer don't spray the engine with water it goes down into the spark plug tunnels and shorts the electric system. Just spray the outside of the radiator and condenser a lot of junk comes out. Remember always change the water pump when changing the timing belt needed or not change it or it will go out a few thousand miles later and the cost is big then it will rip the timing belt to bits. Happy motoring.

You do not need a tester to get the engine codes , on the left ( driver's side ) front top of the engine is a grey box , lift cover and a pin diagram is shown under the cover . turn the ignition on and Jump E1 and TE1 . Read the code/s from the blinking check engine light on dash . For your interest only , go to http://www.lexls.com/tutorials/engine/timingbelt.html to see how the timing belt is changed and the timing marks on the belt and related parts . There is no recommended replacement interval for that belt unless in your case "damage" or the vehicle is used in specific extended low idle conditions . These are not the same belts as used years ago this engine uses a "HSN " type belt (highly saturated nitrile) As for a sensor causing a no start it depends on which sensor so the ans is yes/no . I would advise anyone with a check engine light on to get the codes read.

I have always found my lug key under the trunk floor, to the left of the spare tire, where the tire tools are stored. It is usually found in a little black plastic/vinyl bag. Good luck.

In the LS it originally comes in the drop down tool kit on the left side of trunk .
