Engine won't turn over once engine is warmed up
So I have had this issue with my 07 GS350 for about a month now, and the shop it is currently at is actually having an issue recreating the problem (of course.)
As title says, car starts/engine turns over when it has been sitting for >1 hour. Every morning and evening before/after work, starts with no problem. If I stop at the grocery store on the way home, the car won't even attempt to start. I have to let it sit and try again once it has cooled down. Further information below.
- Starter/Alternator/Battery have all been tested, as well as the connections and wires.
- No codes are being thrown, currently, but cannot further test until the shop can recreate the problem.
Going back and forth with a couple people, we have theorized that something within the car (brain, electrical) is telling it to not even attempt to start due to something being too hot. I am not sure where to even start with this theory. Cat? O2 sensors?
Any information or ideas on how to possibly diagnose this is greatly appreciated.

Could be a neutral safety switch problem. How was the starter tested? If it fails when hot that is not something that can easily be replicated on the bench.

Look at 2:06 see how that gear is sliding into position. I believe yours is not sliding and just spinning giving you that humming sound.
