Does The Pcm Control The Fuel Pump Relay? [Solved]

The fuel pump relay is controlled by the PCM by providing the relay with a ground. The PCM chooses to turn the relay on when it sees the motor is running. If the PCM doesn’t see an indication of the motor running, it will not supply a ground path to the relay and the fuel pump will not receive power.24 Nov 2015
