    All fuses and relays bench test as fine. Will check your suggestion of security system glitch or key switch.

I assume the pump was replaced because it was getting power but no fuel pressure ?
Are you still not getting fuel pressure ?
Spark to the plugs ?
Normal compression when cranking the engine ?
Security light not staying on ?

    Original fuel pump bench tested fine. While we had everything apart replaced it simply due to age. No fuel to injector pump and no spark. All relays and fuses have been double checked. My mechanic says no power to computer. Battery is fine. Mechanic has consulted Lexus mechanic in Charlotte, NC and had completed all checks that Lexus mechanic suggested. Please explain your question about security light. Thank you for your reply.

    I would think the car has a factory installed security system which would disable the engine if the wrong key is used. Something could have happened to that system. Also, has anyone checked the fuse and circuits that are dead to find out why ? Could be something in the key switch too.

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,

brelic
