Default Kpro, AP1, Injectors not pulsing.

So I got Kpro for my 2002 AP1,
I'm getting sparks and i can hear the fuel pump priming.
but when I go to start the car the injectors isn't firing.

I uploaded the PRA s2000 calibration into the ECU
i'm on stock injectors.
with the ignition in the 2nd position.
i'm getting 11.8V on all 4 injectors clip.
I havent had time to pull any codes yet.

but does anyone have any idea why my injectors arent firing?
I pulled the spark plugs and they are bone dry.

This may be a stupid question but you are using the s2000 Kpro and not the RSX unit, correct?

Also, did you change the necessary sensors: crank sensor, and cam position sensors I believe? Hondata will have the correct list on their website

Yes I am using a PRB ECU converted to S2000 by Hondata. and yes I am using all the Kpro crank wheel, sensor, cam wheel, sensor and 06 valve cover.

What does the k-pro say the injector pulse width is while cranking? Are these new or used injectors? How are you determining there is no pulse?

Why don't you enlighten everyone with what the issue actually was?

I called Hondata and they walked me through trouble shooting it. I seriously dont remember we went through like 6 different trouble shooting then I went and try to start it and it started right up.
