What controls a fuel injector?
The amount of fuel injected is controlled by a flap valve located in the engine's air intake. The flap sits beneath the control unit and rises and falls in response to airflow - as you open the throttle, the 'suck' from the cylinders increases the airflow and the flap rises.
What cause no injector pulse?
In case of that, there is no injector pulse or spark, which means that if your ECU has failed in operating in this case you have to get your ECU changed or visit an expert.
What can cause fuel injectors not to spray?
If it does not spray, the problem is the injector or no fuel pressure. The injector should have around 1.3 ohms of resistance, if it is open or zero resistance, it is bad. The injector could be totally clogged as well. Fuel pressure should be 9 to 13 psi.

What is a fuel injector pulse?
Injector pulse width is the amount of time, measured in milliseconds (ms), that a fuel injector stays open (delivers fuel) during a cylinder intake cycle. The typical injector pulse width for an idling engine at normal operating temperature is between 2.5 and 3.5 ms.
What gives power to the fuel injectors?
It is supplied with pressurized fuel by the fuel pump in your car, and it is capable of opening and closing many times per second. When the injector is energized, an electromagnet moves a plunger that opens the valve, allowing the pressurized fuel to squirt out through a tiny nozzle.
How do you check if an injector is stuck open?
No Start, Engine Cranks Okay, Troubleshooting With Basic Tools (No Power To Injectors)
How do you open a stuck injector?
What would cause fuel injectors to stay open?
The injector would stay open if the ground wire were grounded all the time. The injector would stay open if the ground wire were grounded all the time.

Does the ECU control the fuel injectors?
Fundamentally, the engine ECU controls the injection of the fuel and, in petrol engines, the timing of the spark to ignite it. It determines the position of the engine's internals using a Crankshaft Position Sensor so that the injectors and ignition system are activated at precisely the correct time.
What sensor controls the injectors?
The injector control pressure sensor detects the pressure of the fuel feeding the injectors, and sends that signal to the computer so that it can make the adjustments for optimum performance and efficiency.
