Hfs-6 issue(no power)

[Silviasurfer]

Hey guys..... Here is my situation. I had the kit installed in my s14 silvia for 2 yrs took it out and put it in my s15 . Now that it's wired it doesn't come on just the light on the yellow ecu jack comes on nothing elce and yes the injector 12v is hooked up. Any ideas? Every thing Is wired just as it was before what to check for? Is there any upgrades for the hfs6 box
