SR20 Floods when hot

[BSPerformance]

My sr20 keeps flooding itself after I turn it off when the car is hot, problem is not present while its cold.

It will not restart unless I unplug my injectors and start the car and let it run until the fuel burns off. Then reconnect the injectors and it will start.
It will also keep starting aslong as I don't let the fuel pump prime again.

There is no kinks in the fuel hoses.

I've swapped the stock injectors with another set with new o rings and there was no change.

I swapped the stock fuel pressure regulator with another one and still no change.

I swapped coolant temp sensors and still no change.

Checked timing multiple times and is good.

Well I would do some experiments to see what's flooding. Start with the car cold and take off the fuel rail and give it a few cranks and verify the injectors are spraying right and no leaks. Then take the car around the block once or twice to warm it up. Repeat said test and compare results. Report back to this thread your findings.

when the problem is happening take spark plugs out and crank engine to see which cylinder is over fueling. and check for harness damage, if the exposed wires of a damaged harness is making contact with the intake it will cause the injector to do weird things.
