Where is the injector pulse on an ECM?
Okay ecm fires injectors with ground…should have a set of ground wires at thermostat..and one on intake behind where ac pump is or should be. Make sure clean and connected tight.
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
Where does the injector pulse come from in a truck?
I guess no one reads….injector pulse comes from ecm..via ignition module..pickup coil.Once ecm senses 400 rpm,s from engine it takes over. But injectors pulse works off of ground from ecm…you have to have the grounds at thermostat and intake or will not pulse injectors.Grounds for all sensors.
What causes no power to fuel injector pulse?

How does the engine control module ( ECM ) work?
The ECM takes the information from the engine’s various sensors, and uses that information to calculate and tune engine spark and fuel for maximum power and efficiency. The ECM plays a crucial role in newer vehicles, where many (if not all) of the essential functions of the car are controlled by the ECM.

What causes the ECM in a car to fail?
The most common source of ECM failure is in one of the wiring harnesses. If the wires to the transmission or fuel injectors become corroded, they can lose conductivity, leading to a failure. Fortunately, these issues can usually be resolved by replacing the corroded wires. If one of the wires shorts out to the frame, the ECM may fail entirely.

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?
