Katmc_tx Posted July 26, 2007 Share Posted July 26, 2007 Last week I tried to start my 2001 RX300 and it would not start. It sounded like it was trying to turn over but it did not until the 4th attempt and with my having to push the gas. It did not happen every time I tried to start the vehicle but it did happen a couple more times that week. It would also happened at any given time throughout the day not just when the engine was cold. I mentioned it to my husband and we thought maybe we had purchased bad fuel. So over the weekend we added some fuel cleaner to a full tank of gas and decided to give it a couple of days to work through the system. Well here we are on Thursday (the 2nd week) and the engine started fine first thing this morning but when I tried to turn it on again after about 1 hr at the gym it did not turn on. I waited and tried again and then again with pushing the gas and it finally turned on. Any idea as to what the problem is anyone? When we purchased the Lexus we did purchase an extended warranty but it was not a Lexus dealership and therefore not a Lexus warranty. So if I have to take it in to be serviced I'm hopeful the warranty will cover the problem. Thanks for any and all replies. Quote Link to comment Share on other sites More sharing options...
Grumpa72 Posted July 26, 2007 Share Posted July 26, 2007 You have issues with fuel delivery, is my guess. When you turn your key to run (not start) are you able to hear the fuel pump come on for about two seconds. It usually is just a mild humming sound for two seconds. If it's not the fuel pump, it MAY be the fuel filter. When was the last time it was changed? I think that a drive to the dealer is in order if you think it is something other than a fuel filter.

Katmc_tx Posted July 26, 2007 Author Share Posted July 26, 2007 I'll have to listen for that fuel pump next time. As far as the fuel filter I'm not sure since we just purchased the vehicle last September. I'll have my husband look into the fuel filter and maybe have him change it if its not too hard to get to.

TunedRX300 Posted July 26, 2007 Share Posted July 26, 2007 Did you check the thread about how to clean IACV about 8 threads down? Quote Link to comment Share on other sites More sharing options...
blk_on_blk Posted July 26, 2007 Share Posted July 26, 2007 Yep, sounds like a sticky Idle Air Control Valve. It essentially regulates the start up idle, and if it's sticking, you have to give it gas to get the idle to start/stabilize. You don't need to replace it, just clean it. It's a messy job (I did it to our ES300 a while back, for these vehicles share the same engine), but it definitely fixed it. Follow through that thread that TunedRX300 noted... it'll walk you right through the process. Quote Link to comment Share on other sites More sharing options...
