I tryed to have my Car Dynotuned today but when they hooked up the computer to the port it wouldnt communicate at all. I'm the third owner so i have no idea what it could be. Also, I checked the fuses and they are good.

Any suggestions would be welcomed!

No power at the DLC maybe? Take another look at the "CIG/ACCY" fuse.

possible bad Pcm..internal failure...if your car has less than 80k miles on it, its still covered under warranty...get it checked by a dealer.

doubtful it's a PCM issue....

if the tuners cable works on other cars but not yours.... then likely an isssue at your DLC connector

Check the grounds and power there (don't worry about J1850 signal... yet)
