It is hardly ever pleasant to notice an injector noise on your GMC Canyon. It is a noise that appears continually, usually when you accelerate or your engine is idling. However, this indication may be related to different sort of concerns with your automobile injectors. It may not be anything serious, but when a recurrent noise arises, you have to be sure. Specifically since repairing your GMC Canyon’s injectors can be expensive. That’s why our team chose to create this content in order to help you see more clearly, learn about the different plausible failures and establish your problem. To do this, we will first look at the normal running and usefulness of the injectors in your GMC Canyon, then at the plausible causes from which an injector noise may come.
Attributes of the injectors
Injectors are a very fundamental part of the operation of your engine. 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 opportunity, 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 collected from the various sensors equipping the automobile (engine temperature, acceleration level, engine speed, etc.). Their purpose is therefore to inject under high pressure a precise quantity of an air/fuel mixture at a perfect timing to get the best possible combustion in the cylinders.
The different origins of a clicking or knocking noise coming from the injectors of your GMC Canyon
Experiencing injector noises on your GMC Canyon may result from different origins, we will now look into the potential triggers of these. In most cases, the common noise of a faulty injector is of the snap type. Here are the different origins of these noises and the solutions to be applied to get rid of them. If you notice another clicking noise but it is not from your injectors, we advise you to go through this content about clicking noise on GMC Canyon to locate the reason.
The causes for injector clicking or knocking noise GMC Canyon
A clicking or knocking noise from your injectors can be justified by different causes. Indeed, the injectors of your GMC Canyon have three main missions, to control the vaporisation of the fuel, i.e., to convert the liquid into “gas” during injection, to facilitate its combustion. Then, its objective is to deal with the air/fuel dosage and at last the homogeneity of the mixture, always with the goal of improving combustion. If one of these three attributes is modified, the main purpose of the injectors will be disrupted and this will lead to poor combustion. This bad combustion will be a violent explosion in the cylinders due to bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will provoke thoses knocking or clicking noises on your GMC Canyon. The main reason of these concerns commonly comes from a particle that gets into the injectors. The precision of the injector being in the nanometer range, any possible obstruction will inevitably lead to a malfunction of the injector.

The repercussions of injector noise on GMC Canyon
Now that we have examined the several causes for injector noise on your GMC Canyon, we will end by stating the possible end result of malfunctioning one or more of your injectors. Whether only one is obstructed, or broken, or your entire fuel rail is involved, you cannot escape these side effects which can fairly quickly become severe….
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 repercussions experienced by drivers is a serious loss of power. Indeed, if your engine is running on 3 out of 4 cylinders for example, you will undoubtedly have a loss of power
Finally, you risk deteriorating one of your pistons or your engine. Poor combustion will fairly quickly damage your cylinders or pistons and your engine may tighten.
Here are three little tips to limit the risks connected 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 changing your diesel fuel filter regularly>
