ylekiot1 Posted April 26, 2010 Share Posted April 26, 2010 Hi all, I have a 90 ls400 with a noticable noise, inside the cabin only, not from the engine area. It sounds similar to the fuel pulsation I heard from the bad fuel damper I replaced years ago in the engine compartment. But this is near the middle to back of the car that I hear when in the car. I think it is the fuel pump or something related. Has anyone had anything similar happen? I don't want to replace the pump unless I am sure that is the issue. Could it be something else?

kmpdd Posted July 7, 2010 Share Posted July 7, 2010 Is the noise continuous or intermittant based on speed? Quote Link to comment Share on other sites More sharing options...
