Why are there no pulses in the injector?
The injectors are GND’d via the ECU…it could be the wires to the ECU, or the ECU gnds, or the transistors in the ECU…but all of those are quite unliekly to kill pulses to the 2 circuits (batched injecton) (would be two of each failing +)… Re: No injector pulse – why?
Why is my fuel injector # 2 cylinder not getting fuel?
No Pulse I hooked a stethoscope to the injector #2 and it has no pulse. All the injectors are ticking perfectly fine. I switched injectors to stock and have 8 set of these injectors and no matter which injector I use, the #2 cylinder isnt getting fuel. The engine studders and has terrible rough idle at like 550rpm.
Can a car injector be pulsed on a multimeter?
With the car running, it may be hard to see because multimeters are so slow, but you should get a pulsed battery voltage. It will probably just show up as a constant voltage on the multimeter however. If you don’t get it, the injector isn’t being pulsed. Now, since it’s only the number 2 injector, it shouldn’t be the injector driver in the ecu.
Can a PCM loose all 6 injectors at once?
The PCM is set up so that it has individual injector drivers, Meaning that you could loose 1 or 2, but loosing all 6 at one time is very unlikely. Injectors do run off both crank and cam sensors, but mostly off the cam. And when the cam sensor does fail, The PCM goes into default mode, using the last stored run.
What causes no power to 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 Question: What causes no power to fuel injectors?
Can a multimeter be used to check fuel injector pulse?
Therefore, you can see that having a well-functioning fuel injector is vital, and there are numerous reasons why it might stop working correctly. In this article, you will be taken through the steps you should follow to check the fuel injector pulse using a multimeter before you decide to make use of an injector cleaner.
Is there a problem with the number 2 injector?
Now, since it’s only the number 2 injector, it shouldn’t be the injector driver in the ecu. Look at wiring diagrams again and trace the injectors back to the ecu, checking for voltage just like you did before. Most likely you have an open somewhere. found the problem, the wire from the #2 harness to like where the CAS looked a little brittle.
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
