Why does fuel injector not close when ECU fires?
chances are, your injectors are dirty and not compleatly sealing when the injector closes, thus flooding your cylinders by not compleatly stoping the fuel flow into the cylinders. you are suppose to have hot at both wires on the injector untill the ecu fires.
How does the engine control unit control the injector pulse?
Question: What controls the fuel injector pulse? Ans: The engine control unit is the electronic brain that used to control the fuel injector pulse by gathering data from various sensors along the fuel line
How do you test a fuel injector ( ANS )?
Ans: By using a simple diagnostic tool called NOID light, this tool detects a digital signal coming from the ECU and flashes an LED light, so if there is no LED flashing during cranking, this means that there are no pulses coming out of the ECU. Question: How do you test a fuel injector?
What does it mean when there is no injector pulse?
In case of that, there is no injector pulse or spark, this means that is your ECU has failed in operating in this case you have to get your ECU changed or visit an expert.

When do you test the fuel injector pulse?
This test will tell you if the computer is pulsing the fuel injectors open when cranking the engine over. Most of the time this test is done when the engine is cranking over but not starting .

What are the signals for the fuel injectors?
There are three signals which are necessary to operate the fuel injectors. These are the Ne, G, and IGf signals. Inside the ECU, the Ne Signal is used to produce an injection chive signal.
Can a bad fuel pressure regulator cause a misfire?
There are also many causes of engine misfires. It can be a problem in the spark plug or the ignition coil. A fuel injector problem can also cause engine misfires. It is also one of the symptoms of a bad fuel pressure regulator. A problem with this device can lead to low fuel pressure.
What are the symptoms of a faulty fuel injector?
– Rough Idle or Engine Stalls. Because your vehicle is not getting enough fuel or an uneven supply of fuel, the RPM while idling drops below the optimal level and results in a rough or even violent idle. If the RPM falls too low, the car will actually stall and you will need to restart…
How does fuel injection work in an engine?
A big part of that is getting fuel to the engine where it can be combusted to generate power. Your fuel injectors spray gasoline into the intake or directly into the engine cylinders, so that it can be ignited quickly.
How does a BG fuel injector head work?
BG also makes a good cleaning kit for injectors and heads, the injector kit is pumped directly into the fuel rail with compressed air after disabling the fuel pump.
There are also many causes of engine misfires. It can be a problem in the spark plug or the ignition coil. A fuel injector problem can also cause engine misfires. It is also one of the symptoms of a bad fuel pressure regulator. A problem with this device can lead to low fuel pressure.
Is there a buzzer on the fuel injector?
There should be no buzzer or continuity between the Injector ground and chassis ground. Then start the car and while its running check again now you should see continuity between the injector ground wire and the chassis ground. Check to make sure you have not flipped the injector coupler.
