Ls430 engine locked up 2002

I would first start with doing a resistance test on the starter motor. I'm not sure what the spec is, but if the windings in the motor have failed, you should get higher resistance. A bad fuel pump wouldn't cause the motor to not turn, it just wouldn't fire. If it's not the starter or some other electrical issue, I would be looking at finding a junkyard motor or something, I personally wouldn't pay to have someone take this motor apart, too expensive and risky in my opinion. Car-part.com has good motors for about $2500-$3000

Not yet but yes I think trying to turn it will be what I do .. So now all I need is someone to tell me how I should do it and what I should and shouldnt do when attempting this Haha,, but when when I'm able to I know it will answer the biggest questions about the car, it will definitely let me know whether or not my motor is seized

Oil pump won't cause it to not start... but could cause it to seize up... which would be really bad. Have not seen this in a Lexus.
I also assume the fuel pump is working properly and filling up with pressure when you turn the key to the on position. Just ruling out electrical issues.
Almost sounds like time to open it up and see what's going on... any other suggestions?

It sounds like the motor was oil starved and siezed. Not a good thing. They don't all make lots of noise when it happens. I suggest having the car flat-bedded to an indy shop to diagnose. It's probably time to make the new motor v. new car decision.
Brody, is your period key broken? Your posts are really hard to read without that little piece of punctuation.

Also, several mechanics have advised that the crankshaft should only be turned clockwise (when viewed from the front of the engine), although I can't say this from 1st-hand experience.

Yes I know, and missing that little piece of punctuation makes post very hard to read and I do apoligize about all the missing periods but The reason it happens is bcuz I'm legally Blind in one of my eyes and I suffer from disslexia in the other, It usually takes me a really long time to post something because for some reason I have a very hard time figuring out when and where to end the sentence and put periods?!? It gets very Frusterating and Very Time consuming too !! So Last week some guy on another site was complaining about how he couldn't understand anything I posted and how I needed to take more time writing things before posting them !!! So I lost it and Smashed my keyboard on the desk ! And so what key do ya think broke ?? Yep sure did ! So your answer is YES!! My Period keys is Broken along with a few others! Thank God my Exclamation key stll works tho!!! And Hey the good thing is that I'm able to write all my post in half as much time now that I don't have to figure out where to put all my punctuation anymore !!!!

low oil pressure light came but oil levels were good and car sounded great so I figured it was a sensor and I would drive it until I could get it into the dealership the next week since it is about an hour away from where I live , the other day when I pulled Into my driveway after I had came almost to a stop rpms down the engine died , motor didn't make a noise before dying either no rattling no knocking it was just as smooth sounding as it ever was but after it locked up it will not turn over will not do anything ?
Oil pressure warning light comes on but OP keeps driving the car, then at some point later the motor won't crank. My semi-educated long distance guess is that the LS430 motor is likely bricked.

Oh and Btw thanks for your suggestion that I take the car to the shop and get it diagnosed, sometimes the easiest and most obvious way to solve my problems never even cross my mind? Lol , hey if had thought about getting it diagnosed at the shop then I could've just skipped posting all these msgs asking all these questions ? Thanks a lot, Most helpful suggestion ever ! Great Stuff !
