I have a 99 acura slx. used scan tool to check for codes, no communication with pcm. Checked relay--okay. Tried swapping with a known good pcm--still the same. Found C8 fuse on the kick panel blown. put in a fuse car ran good. Shut it off. After 2 hrs, tried starting it, car wont start just cranks. checked fuse--blown again. Put in another fuse, turn car to on position, fuse blows. Couldnt find the direct short. Could somebody point me in the right direction?
