EWS on the X5 controls fuel and crank via the ECU, if it starts and runs when T50 flashed then EWS is working and signalling ECU to release fuel though it should allow start release via T50 at the same time-unusual to have one and not the other, T50 relay is internal in the EWS unit and not replacable seperately.
