When does the fuel injector need to be replaced?
If an injector is faulty on a vehicle with high mileage chances are the remaining injectors are in a similar condition, or will be in the near future. Replacing your injectors as a set ensures each cylinder is receiving the same amount of fuel leading to better performance and improved fuel economy. Since the time required to replace a single injector is about the same as replacing all the injectors it is recommended to replace them as a set.

The number of fuel injector in a car depends on the car engine, model and year. Don't assume that all vehicles are the same.
The Role of the Fuel Injector :
The engine ECU will issue fuel injection commands to the fuel injectors according to the engine's operating conditions. The fuel injection volume is determined by the fuel pressure and the fuel injection time of the fuel injectors. The fuel pressure is controlled by the pressure regulating valve at the fuel rail, and the pressure of the fuel pressure regulating valve is adjusted by the manifold vacuum (engine load), so the ECU can control the fuel injection time, when the engine needs more fuel , The fuel injection time will be longer, otherwise the fuel injection time will be shorter.

(3) Bring your ear close to the rod and listen for clicking.
(4) Repeat these steps for each injector.
Part 2. Ensuring the Injectors Are Receiving Power
(1) Turn the key to the “on” position without starting the engine.
(2) Connect a test light to the negative terminal on the battery.
(3) Locate the two wires going into each injector. And Test each wire for voltage. Then Repeat the process for each injector.
Part 3. Checking the Trigger Circuit for the Injectors
(1) Connect a test light to the positive terminal of the battery. And Have a friend start or turnover the engine.
(2) Probe the opposite wire with the test light. And Look for flashing or flickering light.
(3) Disconnect the wiring clips to each injector and begin the test again.
