Why does my carb spray have no injector pulse?
I have no injector pulse. I have plenty of fuel pressure and both crank sensors and the cam sensor are good. If I spray carb spray through a vacuum hose, it runs fine, but I’m getting nothing through the injectors. What else besides the PCM would control the injectors other than the cam and crank sensors?
Is there an injector pulse on my car?

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
What causes no power to fuel injectors?
The most important signals that determine the accuracy of a signal coming out of ECU to injectors are crankshaft position sensor and camshaft position sensor, so to test a bad injector, you have to check the voltage on the injector when the ignition key is turned on: NO VOLTAGE? , so what causes no power to fuel injectors?

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?
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.
