Try swapping or changing your Coolant temp sensor or check its connection and wires.

Can you turn off CL and tune it in OL for idle n cruise and then try starting it up when warm ?

BUMP
The car is still having this issue, and now that I think of it it started when I was changing my oil and had my car jacked up. I got done and noticed that the wire from the fuel pump to the battery was hanging a little so I moved it up and ever since this the car will not start when hot I have proper fuel pressure, but something that has recently started happening is the car is getting really rich while driving and pressing on the gas at all AFR goes to 10s "maybe lower my gauge only goes to 10.0." With this I was sure it was the coolant sensor, so I went and bought both new OEM Coolant sensors thinking this would fix the issue yet I was wrong. The car will still not start when warm and car is undrivable as the AFR goes way to low when giving it any gas making it really stuttery.
Any help would be greatly appreciated. Also to throw in the fuel pump and injectors are less than a year old.
