    Which motor are you swapped to and from?. This will better my understanding of the situation.

    The ECU (computer) controls the fuel of any car, did you use the ECU for your particular setup?.

    Do you mean you have the D15b1 Intake manifold, ECU, and wiring harness?.

    That is why, you need to use a D15b1 ECU, intake and keep the wiring harness. What is the code on your ECU?. That ECU should be PM5 whereas the D15b7 should be different.

    Sorry about that, I was really tired the other day and thank you for correcting me 97hatch. Do you know what I realized; when I had a problem with my fuel injection on my d16a6 engine I got frustrated and decided to take it ALL apart. I then realized that I tightened the "banjo" nut too tight and fuel wasn't getting into the fuel rail, check that out and GL.

    na i got fuel into the rail just not through the injectors. i have my main relay out and i am resoldering it and i hope that works. i have power to the fuel pump and everything just no signal to the injectors...?
