k24 rsx stalling! PLZ Help

[benzemak24dc5]

stock k24A in base 5 speed. Kpro v4. stock engine harness. No codes. I cleaned the iacv, bought an amazon crank sensor but that could also be bad, changed cam sensors, coils, ect sensor from another engine and it still didn't start. I also installed another new tps, map, new iacv and nothing.

My k24A rsx has been running great for 2 years since I completed the swap. I didn't have any issues until a few weeks ago when I was driving and it felt like it cut power and the idle went to 500 rpm, my oil and battery light came on as if the key was on second position before starting. I was able to give it throttle, and it drove like normal. The next day it stalled while trying to move from a stop. It had little to no throttle response and felt sluggish (later datalogs show that it would go very lean when I did manage to restart it and give it throttle). After restarting it in traffic I was rolling to a stop from about 45mph when it stalled again as I came to a stop. It just shuts off as if I turned the key off. After it sat for 20 minutes it started back up and when i reached a parking space after driving for 10-15 minutes if stalled again at idle. There I changed the fuel pump, but it didn't start, it eventually started after I unplugged my tps.

I can start it up when cold and it will run like normal, once I warm it up and let it idle it will just stall. Before it starts again and will not want to rev (datalog shows it going very lean) my fuel pressure stays at 40 when running and priming. Fuses check out. I tried changing it to open loop, but it still wouldn't start.

First datalog is driving around and it just stalls at the end.
Second shows it stalling several times and restarting again.
Last one is just the cranking. It sounds like it starts for one second then just stalls. It's not a continuous crank.
On the tune I just changed the idle to 800 but it was always at 950. One difference is it will dip after I blip the throttle when its at 800 but that's something i will change back.

Thank you.

You should try your ECU on someone else's car using their calibration and see if it runs as it should. If it does, then you may have a mechanical or wiring problem.

I used an oem ecu when it shut off just cranked and didn’t want to start. I then plugged in the oem Ecu and it started with the oem Ecu. I then reinstalled the kpro and it fired up like normal. All this in less than 5 minutes. If something was wrong with the ecu would unplugging it reset it? Because all I did was swap them.

Yesterday I ran the car and it was idling for a while with the kpro. It was running like normal but today it wouldn’t start even when it was cold. I put an oem ecu and it fired up. I sprayed carb cleaner and it fired up with the kpro. What are the chances the injectors drivers all went bad. Or what could cause it to only firing the injectors for what seems to be one pulse and then not fire them again. The calibration is a hondata basemap but I haven’t made any fueling changes to it.
