Common Causes of Diesel Fuel Injection Pump Problems
diesel fuel injection pump
Are you worried about your vehicle’s diesel fuel injection pump?
It’s important to understand why your fuel injection pump may be
giving you trouble. While an auto shop professional near Ferndale
will need to assess your truck before providing a specific
diagnosis, the following causes are common.
Dirty Fuel
A major cause for fuel injection pump problems is the use of dirty
fuel. Over time, residue builds up throughout your system. Using
poor-quality fuel exacerbates this issue. Bring your vehicle in for
auto repair if you notice sputtering or your vehicle hesitates when
accelerating.
Too Little Fuel
You may also be driving with too little fuel. When your tank gets
too low, the system may fill with air. This can cause serious
issues that will require diesel repair services.
Injector Timing Disruption
Another reason you might need fuel injection pump repair or
replacement is injector timing disruption. Your vehicle’s O-ring or
ball seat may be defective. These are issues that need to be
addressed as soon as possible. A diesel repair technician can tell
you whether the pump can be repaired or needs to be replaced.

fuel speed at the fuel nozzle, The amount of fuel drawn into the
engine depends upon the air velocity in the venturi.

speed to atomize the fuel.
the amount of fuel delivered into the air stream going to the
engine is controlled by a pump which forces the fuel under
pressure.
