3S-GTE JDM 3rd Gen Turbo Engine running troubles

well the car idled fine with the original map, which I found to be bad, but would not rev well cold and not at all warm. cut out a bit as well. anyway, I got a new MAP and now the car wont even run at all. Throwing code 31 only, and when I do manage to get it started it seems to be running on 2 or even 1 cylinder, extremely choppy, very rich, and dies often. The MAP sensor is the only one that seemed to be returning odd numbers, anyone know what code 31 is or have the codes list?

edit: it also will not run with the old MAP anymore

Both MAP's are now returning 7v when plugged in but they only receive 5v
