Okay, I drove my truck monday, no prob. Didn't go anywhere Tuesday, go to start truck in the morning today, nothing. It cranks, and cranks fast, but it seems like there's no spark. I checked the wire leading to the dist. cap, and it has power. I'm trying to avoid pulling a spark plug to check there, but if I absolutely need to I can. I have fuel too. What could cause it to not spark (I'm assuming that's the problem) if I've done nothing to it since the last time I drove it? Am I missing something?
