3 Indicators That Your Common Rail Injector Is Failing and Why You Should Buy a New Auto Part

Solenoid valves are fed by a high-pressure rail. When you maintain the injector properly, it will serve you for a long time without the need for repairs. However, when the system starts to deteriorate, its efficacy reduces, and this can lead to an overall decline in your engine's performance. It is advisable to keep getting your engine checked. You should replace your common rail injector when you notice these issues with your engine.

When There's a Reduction in the Level of Resistance 

A typical rail injector contains a solenoid. The part creates a magnetic field whose pull affects the pintle. When the entire injector is in excellent condition, the solenoid will create enough magnetic force, especially when the entire system is energised. When the injector malfunctions, the solenoid might develop complications such as short-circuiting. Excessive current to the injector will also damage the injector circuit. 

It is best to hire an expert to check your injector when the resistance level goes down. If the problem is beyond repair, they will recommend injector replacement. 

When Cranking Slows Down

Ideally, the injector should take less than five seconds to crank. Cranking is a process facilitated by pressure build-up inside the system. When every part of the injector is working properly, the build-up process happens within a few seconds. The most common reason why the cranking process could slow down is when you have a leak in the system. Leaks interfere with pressure build-up since some of the fluid keeps escaping. 

A competent auto mechanic will check the injector and look for leaks. If they find any, they will check whether the damage is enough for a simple repair. If there are other weaknesses, they might recommend replacing the entire system.

When the Engine's Turbo Starts Having Problems

The third indication you might have to replace your common rail fuel injector is when the turbo function of your engine stops working as efficiently as before. It can happen because the injector is clogged or full of contaminants. When the system has obstructions, it will not feed the needed amount of fuel on time, and the system will begin to lean.

The key is to get an expert to not only assess your vehicle but also check the state of the common rail injector. If it is damaged beyond simple repairs, consider getting a new one from the market and replacing it. For more information about common rail injectors, contact a supplier.
