The modern-day car engine is under considerable pressure, quite literally. This is because technological advancements over the last couple of decades have led to the development of high-performance engines in even the humblest car, designed to get more out of a smaller capacity set up. For this to happen, both fuel and air have to be delivered under a significant amount of pressure and this calls for turbochargers and fuel injector parts in most vehicles. If those injectors are not able to perform correctly then the engine will fail to cooperate, so how can you identify issues in this area?

How Injectors Work

Typically, your vehicle relies on a pump to pull fuel from the tank and inject it into each combustion chamber. The pump has to develop the right amount of pressure before pushing the fuel into the injector and waiting for the ECU to activate a solenoid valve. When this opens the fuel enters the plunger and is converted to a fine mist, which is strategically delivered to each cylinder to provide energy.

Residue Buildup

Problems can be caused when dirty fuel is introduced to the system, as this will cause residue to build up and this grime can clog the fuel injector pump. In a diesel engine, the injector is required to convert the fuel into a fine mist through microscopic holes, and as you can imagine, any type of dirt in the fuel is going to clog very easily. You may notice this when you're trying to accelerate, as the vehicle will sputter or hesitate.

Starving Injectors

You may also run into trouble if you get into the habit of running on fumes. Some people let the tank go down to the empty level before rushing to the nearest fuel station and if so, this will put a tremendous amount of strain on the injectors. The bearings on the fuel pump will quickly wear out without proper lubrication and the pressure level at the engine will reduce precipitously.

Worn Rings

You may also notice performance issues when the replacement O-rings within the fuel injector pump begin to wear out. This will happen in due course and you need to completely rebuild to restore everything.

Taking Action

You can help to avoid too many fuel injector problems if you always buy high-quality fuel, change the filter in accordance with recommendations and never run the tank down towards the bottom. If you do need to conduct a rebuild in the meantime, always make sure that you get high-quality fuel injector parts as well.
