I want to thank you for posting your fix. I used it today it worked.
My battery was drained and then I recharged it. Afterwards the engine would crank and try to catch but seemed like it wasn't getting fuel for fire. I had spark but no fuel. I was convinced something in the security system had immobilized my car. I had a strong battery, good starter and alternator. I had no problem with my car before the battery was drained.
I found this post from 2010 and tried it in 2024. From the fuse box under the hood near battery I removed the fuse box cover. I swapped out the Horn Relay (R16) with the Electronic Fuel Injection (EFI) relay (R17). The relays were the same size, shape and original Denso brand. When I I hit the key it fired right up. Thank You Lexus Owners Club!
