Hi, I'm new here and to Lexus.
My parents have a '98 GS400 and it sounds like it has a fuel pump issue. Can not hear it run when I turn the ignition on. Where is the fuel pump relay? Can I get access to the fuel pump through the back seat?
Is there a on-line service manual I can download? or would a simple Haynes repair manual be good enough.
Thanks,
Nick
