nothing happens when sanner tool is pluged in. Is there a fuse or relay ?

 

A good place to start would be to check the fuse.

 

All fuses good, has anyone had a sanner go bad due to a bad pcm? I ask cuz i replaced the bad PCM, new one worked great till now, CEL came on, still runnin good but can't ck codes even by ignition I have the actron CP9670, thats why i was hoping for a bad fuse or something like that. I'll head to auto parts store & see if theres works till then thanks

 

Try another scanner.

There *should* be power on one of the wires at the ALDL. (where you plug your scanner in) I don't remember WHICH one though......
