What is going on with my GS 400
Wednesday I get out of work and try to start my car and nothing. Just a humming noise no click. After a couple attempts at turning it, I finaly got it to start cranking but no catch. This time when I removed the key it continued to crank.The engie was still trying to turn over and the power steering wheel was moving by itself. After it stopped I finally got it cranked over and the CEL, VSC and VSC OFF came on. Now I read somw threads to find out, but the funny part is that when I took it to my mehanic he said the starrter and both cats were bad. Not only am I not replacing those things but I am not paying his quoted price of over 3200. So I go back to his shop to pick up my car and it starts fine with no codes on at all. What is going on???? ??, confused

The contacts in your starter solenoid are worn...
Your coarse of action should be directed towards rebuilding or replacing your starter.
Since your starter solenoid is getting stuck in the on position, you run the risk of a fire, if you do not notice and remove the negative ground lead from the battery as soon as it happens.
You can DIY for under $30. Plus you labor.
Good luck.

Thanks for the input I wil relay that to my guy that is going to do some work on it. I am not mechanically savy at all. Could that also be the reason that the dash lights came on and are now off?

No not really, but when the starter keeps cranking, the motor is turning and with the key in the off position; it messes with the ECU. I would like to know what codes were thrown. Probably something to do with no ignition signal.

0420 0430 and 1350 which he is going to change the cam position sensor and then on to trouble shooting he cats. Oh contrary to popular belief the bad egg smell on wot means your cat is working properly. I read it somwhere on yahoo answers. Leave it up to you to agree or not

Also anyone interested in perhaps the best video on youtube on testing catalytic converts go to Scott Macdonalds how to test a catalytic converter. He uses a gas probe to measure emissions before and after the cat.

I am not doing it. I am not mechanically inclined. I got a brand new Denso starter and with intake gasket $354 installed. But the cat issues perplex me. I hear differing advice. Since those codes were thrown I've beeen told they are just bad. Then I read up and see ypu can test them and or try and clean them with laqour thinner run through your gas tank. Also heard it could be a bad o2 triping that code. To confusing

$354 is a very fair price for labor...
Before doing anything to your exhaust, verify the proper operation of all of your O2 sensors. A good mechanic should know how to do this with a multimeter and or oscilloscope.
Good luck

I meant I am getting the starter and labor for $354 
I just bought the car. Someone shammed me is what happened. I am going to have a gas analysis done on it. I heard this is the BEST way to tell if your cat is working properly. Before catalytic converter and after catalytic converter. If all the numbers are lower I heard your cat is good. Thabks Frank for input. Also getting timing belt kit Gates for $520 with labor.

A bad O2 sensor will also give you poor numbers on the analysis.
That is why the proper diagnosing procedure is to simply test the O2 sensors first.
A professional grade scan tool can also verify the O2 sensors in real time.
It would be a drag to replace your converters only to find out your same code just returned, of which you have yet to specify.
