Have a pressure test done on the fuel manifold to check for regulator , filter and fuel pump problems. A damper by name only takes the pressure waves out of the system but the regulator if not working correctly will not allow pressure to build up in the manifold.

SOURCE: lexus es300 won't start

I had a similar experience just the other day, i stopped to get gas and turned the car off and when attempting to turn the car back on nothing would happen. Well, let me rephrase the lights inside and out would work as well as the ac and the radio. My initial train of thought was maybe it was the battery so i went and purchased a new battery which was around $100, I installed the new battery and the car still wouldn't start. Does your car make a clicking noise when you turn the inginition key or is it just silent? If it is silent, you might want to check to see if your starter has burned out. Luckly a friend of a friend does his own mechanical work and was able to remove and replace the starter for me. After the starter was replaced the car started right up and ran perfectly. Not sure where u live but in my area a starter ranges in price from $100-200, but they also charge a core fee ranging from $45+, which can be reimbursed if you bring in your old starter to the store. I would suggest getting a starter with a lifetime warranty as well, but thats just a suggestion.

Hope this helps,

I just replaced the head gaskets on my 2002 Lexus es300. And it won't start back up. It's getting fuel and it has spark

Well, an engine needs 3 things to run....fuel, spark, and compression. But they also have to happen in the right time in the right amounts. If you are sure that you have fuel getting into the engine, and you are sure that you have spark at the plugs. I think I would be checking the timing and the compression. And remember, just because you have fuel pressure at the fuel rail doesn't nesissarily mean that the injectors are opening.

I have gas leaking at the end of the fuel rail on a 2002 Lexus ES300. This looks like a plastic cap. Where can I get a new cap?

it is not the cap that you need it will be the fuel pressure regulator and also called the fuel damper for the fuel pressure.....behind the plastic cap is a screw that is set at the factory to regulate the pressure for the fuel at the injecter rail and this screw will back out and will start will need to go to the dealer and show them which one you need cause there are 2 of them and they can show you a picture or the fuel system and you can pick out the one that is leaking.....i hope that this info will help you and if you need any other info let me know.........let me and fixya know if i was able to help you in any way and a thumbs up and a comment on how i did would be appreciated.....good luck and have a blessed day........thanks.....
