SAQ

I had an accident and i damaged the right front wing causing a shortcut to the harness which shut the engine down,i've repaired the harness all electrical working fine but the engine wont start.Replaced the power fc with the OEM ecu and the engine started working, i m sure that the shortcut damaged the power fc,i've opened it and checked it both sides nothing seems burned .
Anyone had a problem like this ?????????any idea on the damage?????
