Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Fuel Delivery
There are 2 fuel delivery systems in use. The first system consists of a low pressure, in-tank fuel pump, a fuel filter/reservoir, and a high pressure electric fuel pump. The second fuel delivery system consists of a single high pressure pump mounted in the fuel tank.
The fuel charging manifold assembly incorporates electrically actuated injectors directly above each engine intake port. When energized, injectors spray a metered quantity of fuel into intake air stream. The length of time that injectors are energized (injector "on time" or "pulse width") is controlled by EEC-IV module.
