A/F gauge doesnt work?!

[o0eclipse0o]

I finally got my new gs-t last week, for 3000. it came already modified for the most part
Hahn racecraft super 16g turbo
apexi 3in downpipe
thermal 3in exhaust
greddy bov, turbo timer, profec b sec II
dejon intake
FMIC
FIC 600 injectors
dsmlink 3.5
and a stage 3 trans

the car runs fine however the problem comes with my a/f ratio gauge, it is connected and all set up, but it isnt on or working? its an autometer digital

is there anything i could be missing or should i just replace the gauge and sensor completely?

Just go over all the connections and make sure the wires are connected! Then check the inline fuse (there should be one for safty). Then of you think it looks ok check where he's taped in for power as he could have a blown fuse for that power tap! If that all fails then it will be the unit but the first would be power so make sure you check every section slowly!
