Ford Mustang Service Manual: Fuel Charging Wiring Harness

Fuel Charging and Controls

The fuel injection supply manifold:

  • receives fuel from the fuel supply line.
  • delivers fuel to the fuel injector.

The throttle body:

  • controls air supply to the intake manifold by positioning the throttle plate.
  • connects the accelerator cable and, if equipped, the speed control actuator cable to the throttle lever.
  • is not adjustable.
  • cannot be cleaned.

The fuel injector:

  • is electrically operated by the powertrain control module (PCM).
  • has an internal solenoid that opens a needle valve to inject fuel into the lower intake manifold.
  • atomizes the fuel as the fuel is delivered.
  • is deposit-resistant. Do not clean.

The fuel pressure relief valve:

  • is used to inspect and relieve fuel pressure.
