The diesel fuel injection pump is responsible for delivering highly pressurized fuel to the engine via the direct fuel injectors. The pump oversees the timing and exact pressure of the fuel going into the engine. It is designed to calculate exactly how much fuel is needed to power the engine at the desired horsepower. It pressurizes the fuel using highly compressed air before sending it to the diesel fuel injectors, which pump the fuel into the combustion chamber.
The fuel is then burned inside the chamber to generate power. The fuel injection pump in a diesel engine will complete this process thousands of times in the scope in less than a minute. The speed of the fuel injection process depends on the rotations per minute (RPM) of the engine.
Most diesel engine fuel pumps use common rail injection. These kinds of pumps do not control the timing and quantity of the fuel. They instead pass the pressurized fuel along to the common rail, which serves as an accumulator for the fuel injectors. The fuel injector will then manage the timing and quantity of fuel used in the injection process.
If the diesel fuel injection pump on your truck is failing, you may have trouble accelerating or starting the engine. It can also misfire when starting or have trouble idling. A bad pump can also lead to reduced fuel efficiency and a sudden loss of power.
