I have a 93 accord that stops running while driving and won't restart right away .it gives a code 15 so I replaced the distributor and reset the ecu with the back up fuse and it still does it then I found out it could be a relay under left side of the dash. My question is what one is it cause there is a bunch under there. Any help would be grateful.

This should answer your question:
