Based on your hot start issue, i believe Andrew nailed your issue.
I would first ensure you have the specified fuel pressure with key on, engine off.
Then work on your "cranking fuel" which controls air/fuel ratio below roughly 400rpm.
Then IAC park position should be tuned to ensure it is opening enough.
Just curious, are you throttling the gas pedal during cranking to get it to start when it is hot? Does it help? That could be an indication that Andrew is on the right track.
Please let us know what you find out

Will do ! Andrew is on the right track. I don't touch the pedal when I start it.
