Need to do more diagnosis. Does it have injector signal, Do you have live data scanner. Is it a Volvo? Sure it could be the e.c.u. but you are going for the throat. We don't even know the vehicle.

Bolt ons, ls6, intake, catless y pipe, its getting fuel to the rails I haven't checked pulse to the injectors, it threw a map sensor code but got it fixed, I've ran the car with my Diablo tuner for live data everything seem ok I don't get any rpm reading tho

No rpm I would be leaning toward the crank sensor circuit or the sensor itself.

How can I repair the crank sensor circuit or where is it located? Is it hard to change the crank sensor?

Talking problem solved

I decided to change cam position sensor, before messing with ecu
and found the wires to cps crimped when i swapped to ls6 intake so took them apart and waraped them up, reinstalled everything and bam it fired right up. Thanks for your time in trying to help me figure it out.
