Geez, seems like im having lots of problems lately. My buddy let me drive his Chevelle the other day, I pressed on the gas and the engine flat out shut off and refused to start. I checked the carb (old holley 4 barrel 4160), totally dry, and no pump shot. I guessed it was a bad fuel pump (mechanical). So I disconnected hose at carb, cranked the engine and fuel shot 10 feet across the driveway. The pump is good. Reconnected the hose, poured some fuel into the carb, it ran for 5 seconds and shut off again. Whats the deal? Bad accelerator pump? Should he just dump it and install a new carb?
