1973 Thunderbird 460 dies after a few minutes
OK, here goes. I bought this car early this summer and drove it about 1000 miles to my home. The previous owner sold the car on behalf of a friend's estate and didn't know much about the condition other than it hadn't really been running much in the past number of years. He had the original Autolite carb rebuilt along with a new fuel pump, points and cap. About half way (500 miles), after really having no engine troubles (86,000 miles on the car) I heard and felt a minor hesitation that only occurred once. I had refilled quite a few times, as you can probably imagine, so I don't suspect I still had bad gasoline, if I even did at all. Maybe I had some ethanol in the mix with today's gas, I dunno. Anyhow, I kept driving and as the next 500 miles went along the car started to hesitate, miss, and back fire more and more. The last 200 miles were nerve racking. The car really wasn't happy. I did actually get it home and it died in front of my house. Yes, 1000 miles just to die at home.
Since then, I've replaced the spark plug wires and vacuum advance (which was certainly shot), but the car will only run for a few minutes and then all of a sudden sputter and die in my garage. I wouldn't even say it gets to temperature before it sputters and dies. Even playing with the gas peddle does nothing to keep it running anymore. I'm too scared to take it out on the road. I did a fuel pressure check by removing the line from the carb and fill a glass jar and it seems fine. Although, the fuel is yellow as urine. Is that ethanol in the mix? I got a jerry can full of premium and added it to the tank, but still no improvement. The fuel filter is clear. The timing seems fine, although new timing belt and gears probably wouldn't hurt, but I don't think that is this immediate problem. People talk about vapour lock and bad coils. Any ideas out there?
