You might have some vapor lock after changing the pump. Disconnect the fuel line at the engine and have an assistant hold the free end over a gas can. Cycle the key on and off to make sure gas is flowing each time. Do this until you see solid fuel with no foam. Reconnect the fuel line, you should be good to go.
