What kind of solenoid does an injector use?
Later types called Electronic Unit Injectors use a built in electrical solenoid to control the opening times of the nozzle.
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 an injector sticking?
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. If the injector is sticking due to wear then it can make a very loud knocking noise which may come and go at random.
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.

Can a fuel injector not receive the correct voltage?
It is possible for the injector to cause issues even if it is receiving the correct voltage. They can clog up, which will decrease the spray inside the cylinder. This, in turn, causes the fuel to not burn completely and will create a misfire.
What’s the difference between high and low impedance injectors?
High impedance injectors are the most common found on cars these days. They will range from 12 to 17 ohms. Low impedance injectors are found on high performance and larger injectors. They have much lower resistance, typically around 2-5 ohms.
Is there no fuel at injectors when bleeding fuel system?
Recently an owner of a TEF-20 wrote in thinking he must be doing something wrong, but he didn’t know what. To use the gentleman’s own words, he was “completely goosed“!
