Fuel System Description: Notes

The fuel injection system has a powertrain control module (PCM) controlled fuel injection pump mounted on top of the engine under the intake manifold. The pump is driven by the camshaft through two gears, one attached to the front of the camshaft and the other attached to the end of the pump shaft. These gears are the same size and have the same number of teeth. Therefore, the injection pump shaft turns at the same speed as the camshaft.
