Power fc problems.

Ok so I bought a used power fc for my s13 sr20det.
Went to turn it on and there is nothing.
Stock computer works no problems.
Is there any possibility that I need to re pin something or did I get fucked ecu from someone who I thought was a legit person on here.
Commander is not Coming on.
No spark or fuel pump turn or anything.
I think it’s fryed.
Anyone with input would be great I want to tune my fucking car.
Everything is new.
Scott.

Power FC ECUs to my knowledge aren’t plug and play.
With that out of the way, It should power up lets start with some more information.
I assume by the post this is in a S13 Chassis?
What SR are you running Redtop or blacktop?
MAF or MAP PFC?
whats the part number on the Power FC?
DO you have any other electronics wired in? (piggy back fuel systems (SAFC, etc), Boost Controllers (AVCR, Etc)
And just for fun what type of stock ECU is running the car now?
