Dieter, so sorry to hear that. I was trolling around the south end of our fair city today and I would have gladly come and kept you company. (You have my cell phone number, right?)
Similar happened to me a month ago, except I was too flustered to think of the fuses. Most days, when I pull her out of the driveway, I take a moment to listen to the fuel pump whirring before I engage the starter. And I had done that in the morning on that day when I left the house. But then the engine rumbled, just as you described, as I wheeled into the place downtown where I was invited for lunch with some colleagues. When I turned the key after lunch, it cranked and cranked but wouldn't catch. What with the traffic noise and everything else around me, I couldn't hear the fuel pump.The flatbed took her all the way to Dan's shop and, sure enough, the fuse for the fuel pump was corroded. Not broken, just corroded enough to be a problem. She has run fine as ever, since that day.
I hope your Blue Tornado is fine by tomorrow. Keep in touch.
