POWER FC is not spraying fuel - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

My head has been hurting over this problem that I have had for the past few days. Today I finally made some headway. So my engine is just cranking and not starting at all. I checked spark, timing and today I checked if my injectors are firing.

I pulled the fuel rail and cranked the car with the fuel rail out. I find that all 4 injectors are not spraying. I then check if I am getting a 12v power to the injectors connector. So I turn the key to ON and probe the injector connector. Since the ECU just pulses the ground, it should have power to the plug. I even crank it with the test light in and nothing. So obviously my ecu is not sending the signal to the injector.

So now I am wondering what the source of this problem could be. I have a power fc and I have never really heard of anyone having problems with them.

Does anyone else know what I could do to get to the source of this problem?
