What happens when injector pump goes out?
The car will misfire and begin to hesitate. It will have a rough idle, not smoothly accelerate and may suffer from power. It may fail emissions testing in some cases. While these problems also be signs of other issues, they also are the first way to alert you to a possible fuel injection problem.
When does the fuel injector open and shut off?
The fuel pump will come on when the fuel pressure within the fuel lines drops to a certain level. Once that level is reached, the fuel pump shuts off. The cycle between on and off time for a fuel pump is measured in seconds. A fuel injector will open when It receives a pulse generated by the car’s computer.
Why do I have a problem with my fuel injection pump?
Fuel injection problems, therefore, are one of the most pressing engine issues to deal with. Whether you’ve experienced fuel injector failure or not, it helps to understand the fuel injector pump, how it relates to engine performance, and also how diesel fuel injection pumps differ from traditional gasoline-powered units.
How does a fuel injector work in a car?
Fuel injectors decrease the pressure within a fuel system. Both fuel pumps and fuel injectors are powered by electricity from the car’s electrical system. The fuel pump will come on when the fuel pressure within the fuel lines drops to a certain level. Once that level is reached, the fuel pump shuts off.
What’s the pressure of a diesel injector pump?
Today’s diesel fuel injection pumps are under pressure – even more pressure than what was once considered “normal.” Around 15-20 years ago, it was common for fuel injector pumps to process fuel in a system at around 10,000 to 15,000 psi (pounds per square inch). But that’s only about half of what engines are expected to do today.

Why is a booster pump used during engine stop?
During engine stop the booster pump is used specially to maintain oil flow in fuel injector. In some design there is also allowance for water passage in fuel injection for cooling purposes. This is provided in these engines to avoid burning and overheating of the nozzle. Common Failures in Fuel Injectors?
Fuel injectors decrease the pressure within a fuel system. Both fuel pumps and fuel injectors are powered by electricity from the car’s electrical system. The fuel pump will come on when the fuel pressure within the fuel lines drops to a certain level. Once that level is reached, the fuel pump shuts off.
