'98 Lexus ES300 Won't Start--But Has New Battery!

About a month ago, my '98 Lexus ES300 wouldn't start. I jumped it, then it worked. This happened almost everyday for 2 weeks. I finally got a new battery and cables installed. Everything was great for a week. Then today, it wouldn't start again. I tried to jump it. But this time, it won't turn at all. Any ideas?

    Thanks Nick. I'll give it a try. On an earlier posting, someone mentioned changing the idle control valve? Any thoughts on this? Carol. (aka LuvMyLex)

If your is exhibiting the same signs as a dead battery it really sounds like your alternator is bad. If you are handy, you can remove the alternator and take it to an autoparts store like autozone and they will test it for you. This is not a hard job to do, usually 2 electrical connections, 3-5 mounting bolts and you have to pop the belt off. Just reverse it to install a new one. Good luck! - Nick

    I highly doubt it would be the valve, I would lean more towards ignition control than a valve, but I need more info to better diagnose. What actually happens when you turn the key? Nothing? Clicking? Engine turns, but doesn't start? For a new battery to fix the issue for a week really seems like an alternator to me.

98 lexus es300 does not start

Vijay, Number one: does it start with a jump? If so, then have the battery load tested. if it is good, look to replacing the starter.
If the battery is good after a recharge, and the load test is good, but it goes flat when parked- usually overnight- then it is the starter too.
Other than that, we get into open circuits, broken switches, etc. LOTSA troubleshooting on thise. Do the basics first, though. Usually you are golden with that. Let us know what your outcome is,

2003 lexus es300 won't start... radio lights and windows work. Tried a jump start, still doesnt work...

Are you saying the engine cranks but won't start, or the engine won't crank ?
If the engine does not crank, you would check for voltage at the starter, the neutral safety switch, and the key switch as well as the ground connections.

My 1999 Lexus ES300 wouldn't start this morning. There's no sound when trying to turn clicking are anything. When I listen under the hood there's a slight click in the alternator

Hi Susie, Turn on the head lights and get someone to observe them while trying to start. If they dim during trying to start, replace the battery. Regards John

2002 lexus es300 not starting battery is good just making strain noise when trying to start.

Either the battery is not holding a "deep charge" or starter is drawing too many amps. Try jump starting see if that works. If it starts with jump, you can have tested at any good parts store, many do it for free. I'd start w/having them load test your battery.

I had a similar problem. My 1998 Lexus ES300 wouldn't start. I had to change idle control valve. I don't have such problems ever since. I read that many used Lexus/Toyota owners had the same problem with that valve.
