Question by c_tackett10: Hypertech Power Programmer?
I ordered a hypertech programmer and the first one didnt work so I sent it back for another one and that one didnt work so they sent me another one..I went outside and pluged it in under the dash in connector and still the programmer didnt come on. Do I have a bad diagnostic connector or is it the programmer

If I do have a bad diagnostic connector,then what should I do to fix it?
