This may be long but I want to describe whats happening. Blazer sat for two weeks, went to use it and it ran fine for about five minutes. I came to a stop and she died. It was real hard to get going again but finally started. The next day she wouldn't start. Disconnected fuel line, no fuel. Replaced fuel pump. Everything was fine for a few short trips around town. Then all of a sudden when coming to a stop she started loading up again and died. It wont run unless I have my foot on the throttle, and runs real rough, as soon as I let up the carb fills up with fuel and she dies. Fuel pours out of everywhere. Any ideas, too much pressure? Needle seat? How to check these things? Thanks for the help. Joe 1980 K5, 350, Rochester Q-Jet 4bbl stock.
