How to check for no pulse on injector?
Check the wiring to the injector. You can check the positive side with a test light with the key on. If that is good you will need a noid light to check the negative pulse from the ECM. A test light will not work for this. Connect the noid light, and crank the engine.
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 pulse on l4-2.5l chevr injector?
no pulse on injector so not getting any gas l4-2.5l chevr… My car has an automatic transmission. Three things are needed in order for the injector to spray fuel: 12 volts from the ECM fuse, ground from the ECM, and fuel pressure. A simple check to test the injector and fuel pressure is to provide 12v and ground manually to the injector.
