Where is the fuel Injector pump on 1997 vortec 5.7?
The 1997 Vortec 5.7L engine doesn't have a single "fuel injector pump" in the traditional sense like some older diesel engines. Instead, it uses a fuel pump located *inside* the fuel tank (an in-tank electric fuel pump) that sends fuel to the fuel injectors. The injectors themselves are located on the intake manifold, one for each cylinder. There's no separate, externally mounted pump to worry about.
