Default '06 IS250 won't start. Fuse help needed.

Greetings,
So my car died and trying to figure out what's wrong. Trying to zero in on the problem by removing as many variables as possible.
A short summery of my problem: I was pulling out of my drive way and my engine suddenly died. And now won't even crank at all.

-AAA tested my battery which is good
-My battery isn't drained and replaced my alternator less than 10months ago.
-All my lights, radio and AC still works
-Im guessing it MAY be my starter, but doesn't explain why my car suddenly died while on.
-Bat terminals cleaned and all connections are good
-Does not crank at all but I hear my starter relay click.

So I want to check my fuses next. Which fuses should I be looking at that might be a reason why it won't start? It may not be a blown fuse, but just trying to slowly find out what's wrong

If it died after pulling out of your driveway, you can probably eliminate the starter. It has nothing to do with the car once the engine is on. Can you pull any codes at all? Just a check vsc light on? If you let it sit for an hour or two and try to crank it, does the engine start and then die instantly?

You say you changed your alternator 10 months ago. Aftermarket, or did you buy a new OEM unit? Did you try jump starting it at all just to test it?

honestly sounds like the fuel pressure sensor if the car sits for like 6 hours and starts up but dies again right away then thats most likely your issue. Let me know if it starts up again

Im not getting any check VSC but I do have my P/S light on after this happened. If it sits for like a day, it will crank then die instantly. It was an aftermarket part, but was "told" it was a quality new part. AAA tried to jump it but didnt crank at all.

I do have a recall that I didnt go in yet for my Fuel Pressure Sensor. Maybe that's it? I hope. Im getting my car towed to a mechanic next week, just to see what the problem is, since Im completely stumped.

Sounds like it's the fuel pressure sensor then. I went through the same thing. Let it sit for a while, crank, start, and then instantly dies. It's DIY'able. Reference this post: https://www.clublexus.com/forums/is-...ml#post9759981

unplug the sensor and try to start the car it may take more then one try to get it started but it will run in limp mode letting the car to at least be moved
