Hi all:

I just bought from a private party a 2001 LS-430. I notice when I turn the key to a position where the instrument cluster powers up, the fuel gauge needle slams from the bottom position to the top position and bounces a few times before settling at the fuel level position. I observed this with a full tank of gas, but I haven't gone through a tank of gas yet, so I don't know whether that happens at low fuel levels. But right now, wit the tank at 3/4, it still does the same thing.

Is this normal behaviour for the 2001 LS-430?

It is NOT normal behavior... I had the same problem in mine and it took 3+ trips to the dealer to finally demonstrate the problem because it was intermittant. turned out they replaced BOTH fuel sender modules and it corrected the problem. Make sure they do BOTH.

Thanks for the response and recommendation. I have an appointment with the closest Lexus dealer on Thursday -- I'll add the fuel gauge needle bouncing problem to the list of items to address along with the specific recommendation to replace both fuel sender units.
