Hey guys wanna pick your brains. I have an 06 gs430 and before the winter the car ran great, Started up just fine. I then put the car on jackstands to have my wheels powdercoated. I disconnected the terminals and had a trickle charger on the battery. Went to hook up everything up 2 weeks later and the car doesnt crank.

-All the lights turn on
-Checked the fuses and they are all good
-Battery is good
-did the lock/unlock trick

any help would be great guys!

since you disconnected your battery, it's very likely that your issue is simply the "anti-theft" system keeping the car from starting. Can I assume that the starter doesn't even crank when you push the button?? You may either have to look in your manual OR call the Lexus service dept to find the sequence...but when my battery was replaced, the selling dealer had to "re-set" the system using the key fob and a series of actions (much like resetting your maintenance lights). Once they did that....thing fired right up like normal. That would be the FIRST thing I'd check.

The display does not tell you anything? Like key not detected, or some such message? No sound of relay clicks under the bonnet?

My 2006 GS430 refused to start a few weeks ago after I had driven away from the house and parked a short time with the radio on. Lights/radio still worked. It was the battery. Dropped in a new one, all good again. That was the original -- 9 years old.

Sounds like you may have popped the main fuseable link

Whats the voltage coming out of the battery?
