I just plugged in my tuner to my car... and it wont work. I plug it into another car and it does! i want to change my 93 octane tune i cant afford the stuff!
I dont think the OBDII port is shot because i passed emissions.
I had this happen when I used my diablosport for the first time, all I did was disconnect the battery and reboot the computer and the tuner finally worked. I would try this first.
Since the post does not include the model year of the car, I can not give a direct answer. Suggest that an inspection of ALL of the fuses be done. You may have to remove each of them one at a time as sometimes it is not visible from the top.
OBTW, if you have a 1999-2004 Mustang GT, the fuse is F1.9(20a) in the battery junction box (BJB) and F2.1(20a) in the central junction box (CJB).
ok i got a test light and tested all the fuses... all are fine..i swapped out the cig. lighter fuse with a friends 20 amp and as i thouht that didnt fix the problem either.
Help!!
dont know. All the fuses seem fine i checked the ones under the hood and inside the cabin. i payed special attention to the fuses that power the DLC too.... all fine. i checked to see if the new fuse blew out too and its just fine.
im really confused!
Did you take the car as suggested to an Auto parts store to have the codes read(yes I know that there aren't any codes). If the ODB2 port works with a regular code reader, this offers information about where the problem could be.
After all of the posts back and forth, you still have not told us the year of the car. Which means that any information that I post about fuse location and connector wire colors may be wrong.
