If you installed it properly you should have done the priming procedure that involves disabling fuel and cranking it over half a min.... did you do this this and remember to replace relays/fuses??
Tapper makes a good point if you did it right step by step you should've pulled these check to make sure you put them back all the one and that none of them have an issue. If you don't see this as a problem or you didn't pull any of them then check to make sure everything is hooked up tight. Check to make sure the gasket is set correctly and its not leating from there or if its blocking the air flow. Then check all your pluming.
