I think I found an error in the book. I think the description of Fuel Pump Control is correct on page 57. I think the Fuel Pump Control Schematic on page 58 is Not Correct.
Page 57 states, the fuel pump relay coil is grounded and 12 volts is applied to the fuel pump relay from the PCM. Page 58 shows the fuel pump relay is supplied with 12 volts all the time, which is Not Correct.
