It is hardly ever pleasurable to listen an injector noise on your Ford Fiesta . It is a noise that appears regularly, usually when you accelerate or your engine is idling. However, this indication may be related to several sort of problems with your vehicle injectors. It may not be anything severe, but when a continuing noise shows up, you have to be sure. Especially since repairing your Ford Fiesta ‘s injectors can be expensive. That’s why our team chose to create this content page in order to help you see more clearly, learn about the different plausible failures and identify your trouble. To do this, we will first look at the normal function and usefulness of the injectors in your Ford Fiesta , then at the plausible triggers from which an injector noise may come.
Functions of the injectors
Injectors are a very vital component of the operation of your engine unit. They were launched to the modern vehicles about 20 years ago. Before their appearance, more conventional carburettor-type intake systems were used, which handled the intake of air and fuel into the engine cylinders. With the injectors, manufacturers now have the possibility, thanks to the injectors pump, to control electronically each stage of the intake process very accurately (quantity of fuel injected, air/fuel mixture) via the analysis of the data received from the various sensors equipping the vehicle (engine temperature, acceleration level, engine speed, etc.). Their objective is therefore to inject under high pressure a precise quantity of an air/fuel mixture at a perfect timing to obtain the best possible combustion in the cylinders.
The different triggers of a clicking or knocking noise caused by the injectors of your Ford Fiesta
Hearing injector noises on your Ford Fiesta may result from different sources, we will now look into the potential triggers of these. In most cases, the typical noise of a faulty injector is of the snap type. Here are the several sources of these noises and the solutions to be applied to prevent them. If you listen another clicking noise but it is not from your injectors, we recommend you to browse this content page about clicking noise on Ford Fiesta to locate the reason.
The causes for injector clicking or knocking noise Ford Fiesta
A clicking or knocking noise from your injectors can be justified by different causes. In fact, the injectors of your Ford Fiesta have three main tasks, to control the vaporisation of the fuel, i.e., to convert the liquid into “gas” during injection, to ease its combustion. Then, its mission is to manage the air/fuel dosage and at last the homogeneity of the mixture, always with the objective of improving combustion. If one of these three functions is modified, the main role of the injectors will be disrupted and this will lead to poor combustion. This bad combustion will be a violent explosion in the cylinders resulting from bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will provoke thoses knocking or clicking noises on your Ford Fiesta . The main reason of these situations in most cases originates from a particle that gets into the injectors. The precision of the injector being in the nanometer range, any possible obstruction will inevitably result in a malfunction of the injector.

The repercussions of injector noise on Ford Fiesta
Now that we have analyzed the several causes for injector noise on your Ford Fiesta , we will end by stating the possible effects of malfunctioning one or more of your injectors. Whether only one is blocked, or broken, or your entire fuel rail is involved, you cannot escape these consequences which can almost instantly become major….
First, you risk destroying your exhaust system in the long run, because the unburned fuel residues that will end up in your exhaust system can corrode the metal in it.
One of the most regular effects felt by drivers is a serious loss of power. In fact, if your engine is running on 3 out of 4 cylinders for example, you will undoubtedly have a loss of power
Finally, you risk degrading one of your pistons or your engine. Poor combustion will almost instantly damage your cylinders or pistons and your engine may tighten.
Here are three little suggestions to limit the risks linked to your injectors and protect you from engine failure:
- Do not drive at the bottom of the tank, as you may absorb impurities
- Use quality fuel
- Think of swapping your diesel fuel filter regularly>
