How to Avoid Injection Pump Failure
Abstract
Every diesel-powered vehicle needs fuel to run, but problems with the diesel injection pump can have a major impact on the operation and efficiency of the fuel system. Unless you're a diesel mechanic yourself, you don't have to know all the ins and outs of diesel repair and maintenance.
That being said, there are a few maintenance tips every diesel owner should know that can keep their diesel vehicle running smoothly. Today, we'll tell you what a diesel fuel injection pump is for, some common problems associated with pump failure, and how to prevent fuel injection pump problems.
What does a diesel fuel injection pump do?
To understand the role of a diesel fuel injection pump, simply take a close look at this part’s name. It’s a pump that injects diesel fuel into the internal combustion chamber of a diesel engine. The fuel enters the injector under pressure and exits as a fine mist through a spray tip.
What causes fuel injection pump failure?
Contaminated diesel fuel - Dirty or subpar fuel can cause debris to build up inside your vehicle’s fuel system. When it does, the residue often impacts the performance of the fuel injector’s spray tip. A buildup of grime, grease, or debris inside the spray tip can lead to engine sputtering or hesitation when you have your foot on the gas and are trying to speed up.
An empty fuel tank - Are you one of those diesel drivers who only fills up when the tank is nearly empty? If so, you might want to change your habits. Driving with a tank that’s low on fuel can quickly cause diesel fuel injection pump problems. That’s because, with little fuel in the tank, the system pushes air through instead of fuel. That can wear out the fuel pump bearings and leave the fuel injectors not getting adequately pressurized diesel fuel.

A dirty fuel injector - Today’s vehicles are complex machines with high-precision parts. A diesel vehicle’s fuel system is no exception. When dirt, debris, or another foreign object makes its way inside, it can wreak havoc on the fuel injector and compromise its performance.
Faulty timing - When the fuel system’s timing is off for any reason, problems ensue. Bad timing of the fuel transfer process could be due to several causes but most often, it’s from faulty O-rings or ball seats.
Electrical Issues - Electrical problems like a faulty relay or wiring in electronic fuel pumps can cause the pump to malfunction.
How to Prevent these problems?
Do not fill your engine with fuel from unknown sources, such as cans or drums where you can't verify its origin (or cleanliness). Also, keep your fuel tank full as often as possible. If a tank is full of fuel, it does not leave room for contaminants to enter.
Fuel filter housings should be drained each year, and the cartridge should be replaced annually.
Don’t let your fuel tank get too low. Whenever possible, aim to keep a ¼ tank of fuel or more at all times. Doing this can help prevent diesel fuel injection pump problems and also ensure you’re not left scrambling to find a gas station that sells diesel fuel.
Consult a professional mechanic about potential problems before performing any modifications to your engine.

How long does a diesel fuel pump last?
On average, a well-maintained diesel fuel pump can last anywhere between 100,000 to 150,000 miles.
The lifespan of a diesel fuel pump can vary depending on several factors, including the vehicle’s make and model, driving conditions, maintenance, and the quality of fuel used.
However, some pumps can last even longer, while others may experience premature failure due to adverse conditions or neglect.
