What happens if there is no injection signal?
What happens if there is no injection signal?
The ECU cannot pulse the injector without an Ne signal and will not start or run if this signal is not present. If the G signal is not present while cranking the engine, the ECU will not be able to identify when to produce the injection signal. The result will be the same, no injection pulse.
Why is my TFI and injector pulse not working?
Mar 10, 2000 The PIP is indeed suspect. Pull the SPOUT jumper out of the harness and see if it makes a difference. Keep in mind that PIP problems may be heat sensitive, and the symptoms may change as things cool off. The PIP is a Hall Effect magnetic sensor that triggers the TFI and injectors.
What are the input signals in a pulse injector?
These are the Ne, G, and IGf signals. Inside the ECU, the Ne Signal is used to produce an injection chive signal. The G signal is used to determine the timing of the injection signals. The IGf signal is monitored for fuel delivery fail-safe. (With Conventional EFI, the IG signal is used to produce the injection drive signal.)
What kind of fuel pump does a red car have?
Car has a 347 stoker with BBK air intake, Mass air, and fuel pressure regulator. Headers, and I assume a bigger out put fuel pump and bigger injectors. After market fuel rails, and a stock distributor. Edelbrock upper and lower intake manifold. Beautiful red car with numerous other upgrades.

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.

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?
