What does it mean when your fuel injector is not working?

Poor Fuel Mileage – A drop in fuel mileage can indicate that an improper amount of fuel is being delivered to the engine. It may be the result of a fuel injector leak or an injector that is not closing. By recognizing the problem and symptoms, you are better prepared to diagnose your injector problem.

Where is the fuel injector located in a diesel engine?

In modern common rail diesel engines, fuel pressures can be over 25,000 psi. Because the injector is seated in the top of the engine cylinder, it is constantly exposed to heat and pressure. This increases the chances of failure over time. Why Causes a Bad Fuel injector? A fuel injector will usually only fail in one of two ways.

How are fuel injectors controlled in a Ford?

This is regulated through sensors, your Ford’s engine computer, and the injectors. The fuel injectors are electronically controlled by the car’s engine control unit.

How can I keep my fuel injector in good health?

Another great way to keep injectors in good health is; to regularly add a fuel injector cleaner to to your fuel tank. Many manufacturers claim that these cleaners, will give your car extra power or increased mpg. They probably won’t, or make much difference, to a car that is running properly.

Is the injection pump getting fuel to the injector?

Currently getting fuel to the inlet of the injection pump but no fuel to cracked injector lines all 8 or if I pull a line completely off. I will be the first to say the fss clicks when it is given power.

What happens if the fuel injector doesn’t close?

If the injector can’t close, cylinder performance is compromised. Whenever the fuel injector pump’s O-rings or ball seats are defective, the timing of the fuel transfer process is disrupted. This is a common diesel fuel injector pump glitch, and usually requires a complete injection pump rebuild or replacement.

Can You backpressure with no fuel injectors?

With no injectors making backpressure, you can do this without too much hassle, and once you see fluid out the injector lines/ports on the IP, you can put it back. Click to expand… I never would have thought of that.

Can a diesel fuel pump injector be clogged?

Diesel fuel pump injectors are high-precision components. They also deal with a tremendous amount of motion and other stresses. One small visitor inside (a piece of dust, debris, etc.) can clog the injector. Worse yet, a microscopic object can leave the injector open all the time. If the injector can’t close, cylinder performance is compromised.

Poor Fuel Mileage – A drop in fuel mileage can indicate that an improper amount of fuel is being delivered to the engine. It may be the result of a fuel injector leak or an injector that is not closing. By recognizing the problem and symptoms, you are better prepared to diagnose your injector problem.

What happens if there is no injection signal?

The ECU cannot pulse the injector without an Ne signal and will not start or run if this signal is not present. If the G signal is not present while cranking the engine, the ECU will not be able to identify when to produce the injection signal. The result will be the same, no injection pulse.

How is a signal injector circuit used for troubleshooting?

Due to the fact that the the output waveform from this circuit produces extremely short ON/OFF periods, the harmonics generated range in the high frequency UHF band. Therefore the generator could be used to for troubleshooting all types audio equipment along with VHF, UHF receiver circuits.

Is there a problem with the number 2 injector?

Now, since it’s only the number 2 injector, it shouldn’t be the injector driver in the ecu. Look at wiring diagrams again and trace the injectors back to the ecu, checking for voltage just like you did before. Most likely you have an open somewhere. found the problem, the wire from the #2 harness to like where the CAS looked a little brittle.
