I'll bet you're on to something on that jumper wire -- timing way off -- cam belt jumped a tooth thing. I asked the guy I bought if from if the timing belt had ever been changed, and he said he didn't know. I think that means "no." The car had been in his family since new, so he probably should have known if it had been changed. I plan to change it to be sure anyway, so I'll get right on that.
And no, I didn't jumper that diagnostic plug. I didn't know what plug it was referring to. Since, I have picked up a Haynes manual for it. New timing belt, first of next week!
Thanks again; you guys are great!
