Strange sound upon startup...
Here are the details...
93 LS400
88K miles
All scheduled services have been done.
Recently the engien has been sounding strange upon start-up. The sound is while the starter is cranking. Normally it produces a very smooth whining sound, but sometimes it just sounds rough. Also, occasionally it makes a very short grinding noise immediately after the engine starts. I haven't had a problem with starting yet (it always starts no matter the sound) but I'd like to figure out why does it sound like this. I took it in to the dealer and they told me it could be an exhaust leak or something else and they wanted $80 to diagnose it. Then my personal mechanic said I may just need to clean my fuel injectors...Well. I don't know what to beleive. What do you guys recommend?

Hey my 91 started having some weird sound like that at start up, a loud clanking ratteling noise. My problem happen to be the water pump started falling apart. Also some of the pullies needed to be replaced.
Have you replaced yours yet?
