Why are my fuel pump injectors not working?
In 2006, diesel fuel production was tweaked to compensate for ultra low sulfur diesel fuel (ULSD), and diesel engine owners have noticed more “dirty fuel” difficulties than before. If your main goal in life was to destroy diesel fuel pump injectors, you’d run your car with the fuel tank as close to empty as possible.
What causes an injection pump to shut down?
The solenoid in the injector being the weakest part is usually the culprit, and can allow fuel to enter the cylinder unregulated. Often the injection pump cannot maintain fuel rail pressure and the engine will shut down due to the ECU fail safe program. If the ECU is interrogated with diagnostic equipment,…
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.
What are the symptoms of a diesel injector failure?
It is unusual for a simple mechanical injector to fail completely and suddenly. The symptoms include smoking from the engine exhaust – usually grey smoke indicating unburnt fuel – this will smell strongly and be rather unpleasant to inhale, making the eyes smart, often more noticeable when the engine is cold.
What are symptoms of an injector problem?
9 Common Bad Fuel Injector Symptoms Rough Idle or Engine Stalls. Because your vehicle is not getting enough fuel or an uneven supply of fuel, the RPM while idling drops below the optimal level Engine Vibrates. A faulty fuel injector will cause the corresponding cylinder to not be able to fire. Engine Misfires. Check Engine Light Turns On. Fuel Leak. Fuel Odor. Engine Surge.
What are the symptoms of a faulty fuel injector?
– Rough Idle or Engine Stalls. Because your vehicle is not getting enough fuel or an uneven supply of fuel, the RPM while idling drops below the optimal level and results in a rough or even violent idle. If the RPM falls too low, the car will actually stall and you will need to restart…
Is it OK to drive with a bad fuel injector?
Though you can still drive or run your car even after noticing some signs of bad fuel injectors problems, it is not advisable for you to overlook any of these bad injector symptoms. The reason is that it could get serious and cause more problems that can damage your car engine.
What is a bad fuel injector?
A car that has a bad fuel injector will often have a rough, or choppy, engine idle. A fuel injector is responsible for injecting fuel directly into the engine cylinder where it is burnt during combustion; if this fuel delivery is compromised, a rough engine idle can result.
What does it mean when there is no injector pulse?
In case of that, there is no injector pulse or spark, this means that is your ECU has failed in operating in this case you have to get your ECU changed or visit an expert.

What causes a fuel injector to leak over the engine?
So, the most common cause of leaky injectors is; the failure of the O-ring, where the injector meets the fuel rail. The O-ring can become, hard and brittle, from the heat of the engine. If it breaks, then fuel can leak out, over the engine. The other way an injector will leak is if, the injector body or nozzle cracks.

Why is my Bosch injection pump not working?
According to Bosch this failure is a poorly “de-burred” rotor. This is a problem in the machining, but has been phased out in later years of production. A seized rotor can be contributed to the lift pump not providing enough fuel to the injection pump.
