92 Sc400 starter click
Hey guys, im new to posting so forgive me if this is in the wrong place but i have a 92 sc400 with a 1uz in it and im afraid the starter went bad, when i turn the key i can hear the fuel pump come on and a clicking sound (only one click) ive done a bit of research but im hoping for some more opinions, i can't afford a mechanic and have a job interview on monday haha... So anything even if its a temporary fix would be great, thanks guys,

First, in the future you should post repair related questions for this model in the SC300/400 Performance & Maintenance sub-forum 
I'm not certain if your starter actually has gone bad or not but if it has, it's a bit of work to replace it on the 1UZ (or any UZ) engine since it's located under the intake manifold and in the middle of the "V" of the engine.
With other cars that have an exposed starter motor you can always whack them slightly on the outside with a hammer to see if the brushes can be jolted into working again but this isn't possible with UZ engines.
IF the starter is the issue it can be rebuilt with a few OEM parts or you can buy a new/reman starter from Denso.

^^ Yes. If there is an issue with one of the battery terminals needing replacement either one is MUCH easier and cheaper to replace than a starter. OEM starters are very, very long lasting and while they can go out with this much age or high mileage it is usually not the first suspect when there are electrical starting issues.
The starter may be the issue but before assuming it is, check everything else first including your car's battery health. Don't get into replacing it unless/until you know for sure that you have to.
FYI, if a factory battery terminal has been determined as faulty, here are the replacement part numbers:
— 90982-06022 Lexus SC300/400 OEM Negative Battery Terminal
— 90982-05030 Lexus SC300/400 OEM Positive Battery Terminal
You can easily unbolt and remove the terminals from the cables for replacement.
