Lexme

New update. Problem has come back within a month of having ECU remapped. Given up really. It does always start but sometimes not until 4th attempt.

Finally got this starting problem fixed. After seeing a few mechanics, it was solved by taking it to lexus and them remapping the ECU. It hadn't been updated apparently. Cost was 1/2 hour of Lexus labour (about £65). The next morning there was a frost but it started first time. Thanks for all the help though guys.

Yeah, Midwifery course, hadn't thought of that! I'm going to see what a couple of garages say, i'll update later. Thanks

Hi, Just bought my first Lexus, a IS 300 Sportcross (02 plate). Engine will not start first time when cold. It normally starts on the 3rd attempt when i give it some pressure on the accelerator. When warm it starts first time no problem. I've read a few of the old posts on this topic, but not sure if anyone really got to the bottom of this problem? I've had a garage test the battery and it's running at 80%. Or is it an ECU problem? If I take it over to a Lexus garage will they run a free diagnostic? Apart from this problem, i'm loving it, but the wifes preggers and I don't want to be sat in car that won't start when it comes to the big day! Cheers for any help
