Hi hope someone out there can help me.I have a 98 gs300 if u turn the ignition key it starts 1st time, runs for 6 seconds then dies. Checked the gas halve a tank so no probs there. Connected a new battery, made no difference. Left key in ignition for 6 minutes to try and re- initiate it, now tried this at every position on ignition. When the key is left in ignition for more than 1minute car rejects the key and wont allow it to start.Take the key out put it back in car starts immediately but then dies after 6 seconds.Tried my second key but that also reacts the same way. Checked the idle, thats fine, checked the fuel lines no can find problem. I gave up and gave the car to lexus, they tried all of the above and the immobiliser yet couldnt find the fault. They decided it must be the ecu so changed that and guess what? that didnt help. Lexus seem to be stumped. Can anyone out there help please, I seem to have the only lexus in the world that has had this problem and this means i cant use her and i dont have another car. HELP

Hi Thanks for your reply I have the six minute rule in all key positions still to no avail. thanks

checked with another key, same response. ???????????????????????? pullin my hair out here!!!!!!!! Just phoned lexus, usual response, bring her in. Might have to do that but have this sneaky feelin that im gonna hear "tut tut hmmmmm big problem and massive bill" Any more ideas anyone. Thanks

checked the idling and its fine, if i acceleratate when she starts that seems to have no effect, checked that shes not choked up. Think the probs with the immobilisor simply because when i leave the key in the ignition for a couple of minutes she wont start at all but as soon as i remove the key then put it back in she fires up straight away but only for 6 seconds.

thanks for the quick responses, theres plenty of petrol in her. when she turns over she starts but shuts down exactly 6 seconds later.If I leave the key in the ignition for a minute she doesnt recognise it and wont start but when i take the key out and put it back in she starts straight away ut still shuts down 6 seconds later. HELP

Hi all, can anyone help please? Took my car into workshop to have bumper resprayed. Got phone call to say car is ready but it now has a problem its a 98 GS300.This workshop only does bodywork and I know the guy and he isnt dodgy. The problem is the car starts but dies after 6seconds. Thought it may be the battery so changed it problem is still there. Was then told maybe the key needs reinitiating was told to leave key in ignition for 6 minutes then fire her up. That didnt work, wouldnt even turn over, but if u remove the key then turn it again car starts first time but dies after 6 seconds. I've not had any probs before and everyone seems to be stumped. Pleas help before this car has to go to lexus where im sure they would love to empty my wallet. Thanx
