Answer Because of differences in the vacuum characteristics of a turbo and non-turbo 300ZX the turbo models (Z31 seriers anyway) have a vacuum pump added under the front bumper that comes on when sufficient vacuum is not available from the engine for only the following....water solenoid for heater, ac/heater controls, cruise control.

On a 1984 Nissan 300ZX the fuel pump turns on with the key. For a couple of seconds to pressurize the fuel system for initial start-up. Once the engines oil pressure has raised to normal operating pressure. The fuel pump remains on.

The fuel pump is inside the fuel tank, which is accessed from inside the trunk.

You'll have to take off the water pump because that is where the thermostat is.
