My windshield wiper was clogged causing rain water to get in my carbon air filter and leaked onto my my passenger floor, I noticed it and didn’t do anything and one day my car stalled randomly and never cranked up, I noticed that my ECM and BCM are in the location the water was leaking. My BCM still give the car life lights windows all that functioning BUT my car won’t crank it turns over but no crank. I have checked all fuses I have changed all crank shaft and cam shaft sensors and I’m convinced it’s my ECM. What is the proper way of fixing this?

 

If you send me the ECU I can test it here. Also can replace as needed.
