Factory service manual
From the 2008 KK factory manual — descriptions, specs, torque & procedures for this part.
FUEL PUMP RELAY📷 1
This vehicle is not equipped with a fuel pump relay. The fuel pump control is done through the TIPM. The TIPM receives an input signal from the PCM. Once the TIPM receives the signal, it will output a 12 volt supply to the fuel pump module turning the pump on.
