I own a 1984 Caprice Classic Estate wagon, 5.0L. I have replaced the timing chain, EGR, PCV, rebuilt the carb twice then replaced it, fuel pump, fuel filter, removed the air conditioning unit, new plugs, distributor, replaced intake manifold gasket, rad, thermostat, muffler, others I?m sure. Anyway, a few dollars spent to bring the old woody up to a very nice condition with only 85 thousand miles on it. The motor has never run better, sounds great.
Here?s the problem. I drove around the other day, about 30 miles, I drove home to drop something off and left the car running. A few steps from the car it stalls, no sputtering, just stops. I get it started fairly easy but rather than drive too far I do a short errand, in the store for 15 minutes and very difficult for it to start. On the way home it just quits, no sputtering, just quits, then it will not start. I left it on the side of the road, walked home. I came back to the car an hour and a half later and it ran like a top for the rest of the day.
There is no vacuum in the gas tank, there is fuel coming from the gas tank to the fuel filter. This problem is so frustrating, any suggestions?
