Just rebuilt the stang and finally got it running this weekend. No real issues encountered immediately and we had it running on and off throughout the day. Anyway, at the end of the day, we finished hooking everything up and plugging in some miscellaneous items, including the foglights, which worked fine. Next thing we know, the car is cranking but not getting spark. Tried another battery just in case, no dice. We found that the plugs appeared to be fouled and gave them a quick clean-up. We were just barely able now to get the car started and running, so I take off to drive it home. I stall out at a light on the way, and sure enough, the car won't start again. I waited about a minute or two before trying again, the car barely starts again but I'm able to get home. Later on I'm showing my friend the car and I had to move it into the garage, it fires right up, twice, without hesitation. As we're looking at some of the work done, when we get to the fog lights, we find they're not working at all. So, in essence, it appears that the problem started right after plugging in the fog lights, then something burned out, now the starting issue is gone. Anyone want to venture a guess on this one? I assume there is a relay for the fogs, where do I find it?
