Three relays are used for the fuel pump and ECCS (computer). This system is designed to prevent pumping if the engine stops running. There is a relay for Ignition, fuel pressure and ignition coil. Loss of any of engine signals (CAS?) at the ECU will stop the fuel pump for example if the car is in a wreck and the engine stops running, the fuel pump will stop instead of pumping fuel out on the ground
