hello, im a new member here to clublexus... have been browsing the forums for a while now trying to troubleshoot issues with my 2000 gs400 with 173k on the odo, anyways. recently had suspension work done on it due to bad balljoints,struts,control arms. but when i drove it back home maybe a few miles it had bogged down and died out while i was driving. which has never happened to me before in this car nor any starting problems. but i turned the key and it fired right back up. parked it and then tried again the next day and no go again.. turns over like it wants to start then nothing happens... then maybe an hour later it fires up no issue. rolled it up onto some ramps in my driveway and found there is a good amount of oil buildup seems the bulk of it is coming from above my alternator.. really trying to figure out why it wont start :/ i love my gs

I know this is obvious, but how much fuel did you have? When I purchased mine, it was low on fuel and did not want to crank at all. I had to fill it up at least half way for it to get back to life. I think maybe these cars are finicky with their fuel pumps. I'm new to the car too so i'm only speculating.

yeah haha iv got over a half tank. and have replaced fuel pump maybe 3 months ago im thinking it might be oil leaking down onto some electrical or something.. i keep waiting to say maybe even spark plugs or coils... but i feel my check engine light would come on for that.

The power steering pump sits above the alternator so what you have is most likely a leaking steering pump. It's possible your alternator is going out so it's not properly charging the battery, hence the trouble starting. That or your starting is going out (very common on GS400)

i see. altho i did just have to put oil in because it was really low. but there is a trail of gunk that comes from where the reservoir connects to the hose on the bottom. and if my alternator is bad wouldnt my battery die? its been like this for a few weeks now. and it still turns over just fine just no fire.

first try of turning key it seems to almost fire but dies out almost instantly. then the following tries are just endless turning over. going to take it in somewhere to have someone diagnose it hopefully...

Make sure the immobilizer is not losing transponder signal.
In other words; make sure the security light is off and not blinking when the key is in.
Good luck

just went and tried it and its flashing when its out then stops when i put it in as it should?. still no start though.. im starting to think its probably the starter. but im unclear of the difference between the motor turning over and it just cranking ?
