Hi, Y'all! Mystery solved--it was raw gas fumes! The fuel pressure regulator finally sprang a major enough leak that it still reeked by the time I got it to the repair shop this morning. Apparently, it has been leaking intermittently since last June when I first noticed the problem. It had been hard to start when hot for a couple of weeks, and yesterday would not start cold until I depressed the accelerator; it would crank fine, just not turn over. Being a child of the carburetor-and-distributor-cap era, I thought I was giving it gas to start when I depressed the accelerator, but the service writer told me what actually happened was that this opened the throttle to allow enough air into the system to start it. In any case, it worked well enough to achieve my objective, which was to get the car started to get it to the shop. Thought y'all might appreciate hearing the solution! Sherry
