Would'nt Start (Panic)
 

Got in the car acted normal, got to the store went in stayed about 15 min and came out and car would not start. Tried the key and still would not start. The key turns on and everything works but it won't go on over to start. Waited about 5 mins and it started up like nothing was wrong. What is going on?
PS: The car is UL 430 with electronic key.
Thanks Joe

man....i have no idea......thats crazy

what year is it?

Could be early sign of:
1. dieing battery
2. starter???
3. loose battery connections
4. a rare fluke

Battery
 

New battery in car after this happened once before. Sorry it's a 05. Could the fob battery be going down.

maybe the starter thats my geuss

Not the starter, if it is, you can turn the key but no click from the starter.
Maybe the battery in the key???
Or an once in the blue moon fluke???

My guess would be a loose battery connection. I had that problem before on my GS300 and after cleaning and tightening the battery bolt, everything worked fine after that. 2nd guess would be battery cells are going dead.

DanozLS430...

Key knob on dash
 

I'm sorry I didn't explain myself better. The key knob on the dash would not go over far enough to engage the starter. I tried pushing in and it still would not go into the start mode. See first post for the rest.
PS: Do you have to push in from the beginning to go to the start position? Or can you have the key in the acc. mode and than push in for it to start. Thanks Joe

Maybe the steering wheel was locked?

Was the LS 430 parked on an incline? There is a safety feature which prevents the key knob from turning to start mode, if the car is parked at an incline and the steering wheel turned to one side. This is to prevent the car from sliding out of position when starting; I experienced this once on an LS 430 when parked at a gas station (very slight angle, but still) and Lexus Roadside Assistance advised that the car not able to start (key knob would prevent ignition) was intentional; just straighten the wheel and the car could start normally IIRC. Nothing wrong with the car in that instance.

Turn the steering wheel a little while turning the start knob. Grand LS 4 maybe correct on this.

The steering wheel not straight on an incline would be my two pennyworth!

Had this "problem" in my LS400 and my Sienna--- it was usually just turning the wheel. I do remember freaking out the first time I encountered it.
