Help with EVO 8 ecu

Im trying to go back to my stock ecu for inspections but the car wont start and wont connect with the tactrix cable. Im trying to access my ECU to see what kind of faults are showing and look over my ROM but no luck. Ive tried various versions of evoscan and ecuflash and none will connect. I will pay someone if you can get it to run.
