The function of a fuel injector is to mix the fuel in the car’s engine with air thus allowing the engine to run in a more smoothly manner at high and low temperatures. However the fuel injector and the fuel pump can both get blocked causing malfunction. Luckily there are some easy techniques that can be used for fixing a fuel injector before a new fuel injector can be purchased.

First of all, determine whether the problem is caused by the fuel pump or fuel injector. In case the fuel pump is not running completely or is running slow, then the power supply has to be checked. The emitted from the pump has to be measured by attaching a static output pressure gauge to the fuel rail. The fuel injector filter should be checked because these filters frequently get blocked. The blocked filters can be replaced at a very low cost rather than replacing the whole injector. Blocked fuel injectors and fuel injector filters are the very frequent problems that cause the fuel injector to work improperly. The tip of a thin metal rod has to be placed on the malfunctioning fuel injector. Use a hammer for gently tapping the other end of the metal rod. Make to tap on the fuel injector while the engine is start and running. Tap slightly harder if the injector still not working. You would have to consider having a replacement in yiwu market in case the fuel injector fails to work because it is possibly shot.
