What would cause no spark and no injector pulse?
With no spark and no injector pulse, you could have a bad crank sensor or a bad IC module, or there could be a problem with the wiring in between them…..
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.

Why is my N16 Pulsar engine not working?
If you have fuel pressure and hear ticking your injectors are fine and working. Crank angle sensors tell the ECU where the crankshaft is in relation to everything, so it controls the spark and injector pulse. No sensor means no spark or injector pulse, therefore no engine……..
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?

Is there a spark from the fuel injector?
No spark from all of the Coil-On-Plug Ignition Coils. No fuel injector pulses from the fuel injector connectors as tested using a Noid Light.
How to test no spark no start test?
No spark from all of the Coil-On-Plug Ignition Coils. No fuel injector pulses from the fuel injector connectors as tested using a Noid Light. P0335: No Crank Sensor Signal Detected. P0336: Inconsistent Crank Sensor Signal Detected.
