evo 8 throttle body tps issue

Okay so here is the basic info, did the dohc swap a way back never fully finished. So stock 4g64 bottom end, KIA head, evo8 intake, evo8 tb. Now the tb didn't come with a tps I put on the stock gallant but later saw they are not the same. Now I'm only just starting the car up to check for leaks. However when I hit the gas it doesn't rev its dies out. Just wondering if its possible that the different position would be grounding out instead of give ng positive voltage.
