What causes no spark, no injector pulse condition?
Could ignition switch cause this no spark, no injector pulse condition. Tough problem. Obviously you know that for an engine to run it needs: I’m assuming that this is your vehicle, it worked before, and now it doesn’t. (i.e. the engine’s four cycle functions are correct.
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 spark signal come from on a car?
No code indicates that is not what’s stopping your car from starting up. Note that the spark “control signal” originates from inside the Powertrain Control Module. I believe your still uses IGBT (insulated gate bipolar transistors) for spark controls.
Why do I have no spark on my ignition switch?
I have changed both crank and cam sensors and have power to all four coil over plug coils and to one side of the injectors on all with the key on but am not getting spark to spark plugs when cranking.I have power to fuse and changed relay to ignition. Could ignition switch cause this no spark, no injector pulse condition. Tough problem.
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.

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 kind of fuel does a spark ignition engine use?
We have seen two types of fuel system, fuel injection system in diesel engine and petrol or octane run the engine. We have a focus on the Spark Ignition engine (SI Engine), which is run by Octane or Petrol. What is Fuel Injector?
