Turn the key to start it,it starts no problem,but when you let go of the key it shuts off! if I hold the key it keeps running,but while holding the key at the sametime,then put the car in Drive it shuts off! I've changed the Ignition,the ingnition switch,a new key,I just dont know the hell is wrong!

 

hmm make a vid and post it. same thing happend with my es.

first make sure there is no vacuum leak
also what did you do to the car last before the problems arose
using the rite gas
clean gas
clean filter


check all the easy cheap things fuses ect

 

what up jubay ... has the new key been programmed to the security system. i mean does it unlock and lock the doors remotely.

 

You need to keep the car running first without the key, that's your first problem.

Have you tried checking your relays??

 

so you saying when you hold the key on start car starts and starter shuts by it self? I really dont understand how its possible...usually when you hold the key all teh way to the right, starter will keep spining.

 

when I hold the key the starter is still spinning

 

I've checked the relays,someone suggested that i should just change the whole steering column

 

take out the starter relay. put a wire between 2 and 5 pins of the fusebox where the relay would sit. crank it again. see what happens.

make sure the key is in the ON position.

if the car doesnt stay on. perhaps the ignition cylinder is faulty.

 

well i wouldnt keep doing it..your starter wont last much longer if you keep doing it..but as far as advise sorry man i really never heard of anything like that before.

 

yeah i wouldn't wanna burn out the starter, that will just put a bigger hole in your pocket, crazy and rare problem. i hope you get it solved man. GL

 

I'm not an experienced mechanic, I just do some of the more fun and simple do it yourself jobs. Sounds to me like you've got a bad ignition switch. Does the car lurch forward right after you shift into drive and right before shutting off? The converter clutch inside the torque converter might be engaging when it's not supposed to. Personally, I would call an experienced Lexus mobile mechanic.

 

nah the car doesnt lurch at all,but thanks,I might just have to take it to the dealer

 

Check the 30a ign fuse in your engine bay first

 

Then look in to your ignition harness behind your key. You will find 2 wires (brown) (brown with white stripe) cut them and connect them together from harness side.Then start your car

Hope this helps.
