J-Spec Swap Won't Start: Injectors Do Not Fire

I made a Jspec engine swap.

The car wont start. The reason for that is that my injectors dont work...They do not spit. My fuel pump works, my fuel rail is fuel and I have spark. I can only assum the injectors dont work.

I have low impedance injectors (on center plugs) and an on-center injector plugs wire harness, which I can only assume is low impedance to. My ECU is an N332.

My injectors are new also.

Any suggestions?

Also, is my fuel pressure regulator supposed to be block when I blow through it? I check my return and I had no fuel. It jams in the pressure regulator. So I took it off, tried to blow in it but couldn't. Is that normal?

Thanks!

Please don't bump your topic. Bumps are not allowed in this forum as the clog up topics. If you had used a subject line better then "another problem" maybe more people would have been interested in reading your topic. I've edited the subject to something more appropriate.

Now, for the car. When you crank the car do you have spark? If there is no spark, then the ECU is not receiving power or a signal from the CAS.

Is the AFM plugged in? In my experience, the ECU will not fire the injectors unless the AFM is connected.

Could it be that your fuel lines are reversed, that's why your injectors aren't "firing??""

no, I figured it out already.

The guy that sold me the wire harness did not give me the resistor pack with it....

Thanks
