How long has the ""new"" pump been sitting? I've heard of people having issues with the fuel metering valve varnishing and sticking after sitting for extended periods.
I couldn't tell you specifics, but it's been mentioned on here before that there's a way to pull the top off the IP and make sure the metering valve is moving freely.
