It is hardly ever enjoyable to notice an injector noise on your Ford Ranger. It is a noise that comes up continually, usually when you accelerate or your engine is idling. However, this sign may be linked to different sort of trouble with your automobile injectors. It may not be anything serious, but when a repeated noise happens, you have to be sure. Specifically since replacing your Ford Ranger’s injectors can be expensive. That’s why our team chose to create this content in order to support you see more clearly, learn about the different plausible failures and distinguish your issue. To do this, we will first look at the normal running and usefulness of the injectors in your Ford Ranger, then at the plausible reasons from which an injector noise may come.
Attributes of the injectors
Injectors are a very significant component of the operation of your engine unit. They were brought in to the modern vehicles about 20 years ago. Before their arrival, 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 precisely (quantity of fuel injected, air/fuel mixture) via the analysis of the data obtained from the various sensors equipping the automobile (engine temperature, acceleration level, engine speed, etc.). Their aim 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 Ford Ranger
Hearing injector noises on your Ford Ranger may result from different origins, we will now look into the potential causes of these. In general, the regular noise of a faulty injector is of the snap type. Here are the several sources of these noises and the solutions to be implemented to stop them. If you notice another clicking noise but it is not from your injectors, we encourage you to read this content about clicking noise on Ford Ranger to find the reason.
The reasons for injector clicking or knocking noise Ford Ranger
A clicking or knocking noise from your injectors can be justified by different reasons. In fact, the injectors of your Ford Ranger 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 task is to deal with the air/fuel dosage and finally the homogeneity of the mixture, always with the goal of improving combustion. If one of these three characteristics 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 because of bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will induce thoses knocking or clicking noises on your Ford Ranger. The main reason of these trouble generally comes from a particle that gets into the injectors. The precision of the injector being in the nanometer range, any possible blockage will inevitably end in a malfunction of the injector.

The consequences of injector noise on Ford Ranger
Now that we have examined the different reasons for injector noise on your Ford Ranger, we will end by stating the possible consequences 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 consequences which can almost instantly become critical….
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 known repercussions experienced by drivers is a severe loss of power. In fact, if your engine is running on 3 out of 4 cylinders for example, you will obviously have a loss of power
Finally, you risk deteriorating one of your pistons or your engine. Poor combustion will almost instantly harm 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 swapping your diesel fuel filter regularly>
